TECHNOLOGICAL FIELD
[0001] Embodiments of the present invention relate to a wetsuit. In particular, they relate
to a wetsuit for improving the performance of a swimmer.
BACKGROUND
[0002] A swimmer is subject to friction drag, pressure drag and wave drag. Friction drag
is due to the constant collision and rubbing of the swimmer's body against the surrounding
water molecules.
[0003] Pressure drag builds as a swimmer picks up speed. Water builds up, for example, around
the swimmer's head causing an increase in pressure in the frontal region of the swimmer's
body and creating a pressure differential between the two ends of the swimmer's body.
[0004] At racing speeds, the swimmer is further impeded by wave drag, which is caused by
waves created by the swimmer during swimming.
[0005] WO 2013/082173 A1 discloses a wetsuit that is equipped with strips on the sides of the leg portions.
The strips have a thickness that is less than the thickness of the material used to
form the bulk of the leg portions.

DETAILED DESCRIPTION
[0009] Figs 1A and 1B illustrate front and rear elevations of an external surface of a shell
80 of swimwear. In this example, the shell 80 is made from a material that is permeable
to water and air. In this example, the swimwear is a swimming jammer. The shell 80
of the jammer is formed of a plurality of panels 34, 36, 38, 44, 46, 48, 50, 52 and
54 in the illustrated example. The shell 80 includes a first side panel 34, a crotch
panel 36, a second side panel 38, a first upper front thigh panel 40, a second upper
front thigh panel 42, a first lower front thigh panel 44, a second lower front thigh
panel 46, a first upper rear panel 48, a second upper rear panel 50, a first lower
rear panel 52 and a second lower rear panel 54.
[0010] The jammer is arranged to be worn such that a waistband/waist strap/stiffening member
4 is positioned at or below the navel of a wearer and above the iliac crest of the
greater pelvis of the wearer. A drawstring 2 may be provided above the waist strap
4, as shown in various appended figures.
[0011] In some embodiments, a gripper strap made from silicone may be positioned on the
inside of the waist strap 4 and/or adjacent to the drawstring 2.
[0012] The term "seam" as used herein is considered to relate to a boundary between two
portions/panels of material.
[0013] A first longitudinal seam 6 is present in the shell 80 which is arranged to extend
from a first hip region 1001 of a wearer of the jammer to a first lateral thigh region
1002 of the wearer. It can be seen in Fig. 1A that the first longitudinal seam 6 provides
a boundary between the first side panel 34 and each of the crotch panel 36, the first
upper front thigh panel 40 and the first lower front thigh panel 44. In this example,
the first longitudinal seam 6 extends, at the front of the wearer, from the waist
strap 4 of the jammer to a lower extremity 31 of a first leg portion of the jammer.
[0014] A second longitudinal seam 8 is arranged to extend from a second hip region 1003
of the wearer to a second lateral thigh region 1004 of the wearer. The second longitudinal
seam 8 provides a boundary between the second side panel 38 and each of the crotch
panel 36, the second upper front thigh panel 42 and the second lower front thigh panel
46. In the illustrated example, the second longitudinal seam 8 extends, at the front
of the wearer, from the waist strap 4 of the jammer to a lower extremity 32 of a second
leg portion of the jammer.
[0015] A first crotch seam 14 extends upwardly at the front of the wearer from a crotch
region 1005 of the shell 80 to the first longitudinal seam 6. The first crotch seam
14 provides a boundary between the crotch panel 36 and the first upper front thigh
panel 40. A second crotch seam 16 extends upwardly at the front of the wearer from
the crotch region 1005 of the jammer to the second longitudinal seam 8. The second
crotch seam 16 provides a boundary between the crotch panel 36 and the second upper
front thigh panel 42.
[0016] A first inner leg seam 20 provides a boundary between the first upper front thigh
panel 40 and the first upper rear panel 48, and between the first lower front thigh
panel 44 and the first lower rear panel 52. A second inner leg seam 21 provides a
boundary between the crotch panel 36 and each of the first upper rear panel 48 and
the second upper rear panel 50. A third inner leg seam 22 provides a boundary between
the second upper front thigh panel 42 and the second upper rear panel 50, and between
the second lower front thigh panel 46 and the second lower rear panel 54.
[0017] A first lateral thigh seam 24 is arranged to extend laterally across the front of
a thigh of a wearer of the jammer. The first lateral thigh seam 24 extends from the
first longitudinal seam 6, in the first lateral thigh region 1002 of the wearer, to
a first inner leg region 1006 of the wearer. The first lateral thigh seam 24 provides
a boundary between the first upper front thigh panel 40 and the first lower front
thigh panel 44. The first lateral thigh seam 24 is positioned such that the first
lower front thigh panel 44 is smaller than the first upper front thigh panel 40.
[0018] A second lateral thigh seam 26 is arranged to extend laterally across the front of
a thigh of a wearer of the jammer. The second lateral thigh seam 26 extends from the
second longitudinal seam 8, in the second lateral thigh region 1004 of the wearer,
across the front of the thigh of the wearer and to a second inner leg region 1007
of the wearer. The second lateral thigh seam 26 provides a boundary between the second
upper front thigh panel 42 and the second lower front thigh panel 46. The second lateral
thigh seam 26 is positioned such that the second lower front thigh panel 46 is smaller
than the second upper front thigh panel 42.
[0019] A gluteal seam 18 extends from the crotch region 1005 of the wearer upwardly through
a gluteal region 1008 of the wearer to the waist strap 4. The gluteal seam 18 provides
a boundary between the first upper rear panel 48 and the second upper rear panel 50.
[0020] A third longitudinal seam 10 is arranged to extend from the first hip region 1001
of the wearer to the first lateral thigh region 1002 of the wearer. The third longitudinal
seam 10 provides a boundary between the first side panel 34 and each of the first
upper rear panel 48 and the first lower rear panel 52. The third longitudinal seam
10 extends from the waist strap 4 and extends, at the rear of the wearer, to the lower
extremity 31 of the first leg portion of the jammer.
[0021] A fourth longitudinal seam 12 is arranged to extend from the second hip region 1003
of the wearer to the second lateral thigh region 1004 of the wearer. The fourth longitudinal
seam 12 provides a boundary between the second side panel 38 and each of the second
upper rear panel 50 and the second lower rear panel 54. The fourth longitudinal seam
12 extends from the waist strap 4 and extends, at the rear of the wearer, to the lower
extremity 32 of the second leg portion of the jammer.
[0022] The first, second, third and fourth longitudinal seams 6, 8, 10, 12 are curved in
shape in this example, such that an upper portion of each side panel 34, 36 is larger
in width at the top and bottom than in the middle. Fig. 1C illustrates the shape of
the first side panel 34. The second side panel 38 has the same shape as the first
side panel 34.
[0023] A third lateral thigh seam 28 is arranged to extend laterally across the back of
a thigh of a wearer of the jammer. The third lateral thigh seam 28 extends from the
third longitudinal seam 10, in the first lateral thigh region 1002 of the wearer,
to the first inner leg region 1006 of the wearer. The third lateral thigh seam 28
provides a boundary between the first upper rear panel 48 and the first lower rear
panel 52. The third lateral thigh seam 28 is positioned such that the first lower
rear panel 52 is smaller than the first upper rear panel 48.
[0024] A fourth lateral thigh seam 30 is arranged to extend laterally across the back of
a thigh of a wearer of the jammer. The fourth lateral thigh seam 30 extends from the
fourth longitudinal seam 12, in the second lateral thigh region 1004 of the wearer,
to the second inner leg region 1007 of the wearer. The fourth lateral thigh seam 30
provides a boundary between the second upper rear panel 50 and the second lower rear
panel 54. The fourth lateral thigh seam 30 is positioned such that the second lower
rear panel 54 is smaller than the second upper rear panel 50.
[0025] Figs 2A and 2B illustrate front and rear elevations of an internal surface of the
shell 80 of the jammer. In Figs 2A and 2B, the shell 80 has been turned inside-out
to show the internal surface. Fig. 2C illustrates the internal surface of the first
side panel 34.
[0026] It can be seen in Figs 2A, 2B and 2C that a lower extremity of each of the first
side panel 34, the first lower front thigh panel 44 and the first lower rear panel
52 has been turned upwards to form a first hem 58 on the inside of the shell 80 of
the jammer. Each of the second side panel 38, the second lower front thigh panel 46
and the second lower rear panel 54 has been turned upwards to form a second hem 56
on the inside of the shell 80 of the jammer.
[0027] First and second gripper straps 60a, 60b are located on the first and second hems
58, 56, and are configured to grip a wearer's leg around its circumference. In this
example, the first and second gripper straps 60a, 60b are arranged to grip the wearer's
leg at a position around the thigh, adjacent to and just above each knee. The gripper
straps 60a, 60b, may, for example, be made from silicone.
[0028] The jammer comprises both the shell 80 illustrated in Figs 1A to 2C and a lower body
harness 5. Figs 3A and 3B illustrate front and rear elevations respectively of the
internal surface of the jammer 100 (that is, the jammer 100 in its inside-out configuration),
including the shell 80 and the lower body harness 5. Fig. 3C illustrates an internal
surface of the side panel 34 of the jammer 100.

them together, for instance.
[0063] The first gripper strap 60a is coupled to one or more of the first, third, fifth
and seventh longitudinal straps 106, 110, 206, 210 and the inner leg strap 120. In
some examples, the coupling is provided by attaching the first gripper strap 60a directly
to one or more of the first, third, fifth and seventh longitudinal straps 106, 110,
206, 210 and the inner leg strap 120 (e.g. by stitching). Alternatively, the coupling
may be provided merely by means of the interconnection between the hem 58 and the
first side panel 34, the first front thigh panel 44, and/or the first lower rear panel
52.
[0064] The second gripper strap 60b is coupled to one or more of the second, fourth, sixth
and eighth longitudinal straps 108, 112, 208, 212 and the inner leg strap 120. In
some examples, the coupling is provided by attaching the second gripper strap 60b
directly to one or more of the second, fourth, sixth and eighth longitudinal straps
108, 112, 208, 212 and the inner leg strap 120 (e.g. by stitching). Alternatively,
the coupling may be provided merely by means of the interconnection between the hem
56 and the second side panel 38, the second lower front thigh panel 46, and/or the
second lower rear panel 54.
[0065] As described above, the waistband/waist strap 4 of the jammer 100 is arranged to
be positioned at the navel of the wearer, such that it is located at or above the
iliac crest of the greater pelvis of the wearer.
[0066] The waist strap 4 is arranged to provide tension in the jammer 100, when it is worn,
at or above the iliac crest of greater pelvis of the wearer. The arrangement of the
first, third, fifth and seventh longitudinal straps 106, 110, 206, 210, the first
lateral thigh strap 124, the gripper strap 60a around the first hem 58 and the third
lateral thigh strap 128 is arranged to provide tension in the jammer 100 just above
the wearer's first knee, specifically in the first lower front thigh panel 44 and
the first lower rear panel 52.
[0067] The arrangement of the second, fourth, sixth and eighth longitudinal straps 108,
112, 208, 212, the second lateral thigh strap 126, the gripper strap 60b around the
second hem 56 and the fourth lateral thigh strap 130 is arranged to provide tension
in the jammer 100 just above the wearer's second knee, specifically in the second
lower front thigh panel 46 and the second lower rear panel 54.
[0068] The tensioned portions of the jammer 100 just above the knees of the wearer and at
the waist are interconnected by the first, second, third, fourth, fifth, sixth, seventh
and eighth longitudinal straps 106, 108, 110, 112, 206, 208, 210, 212 and by the inner
leg strap(s) 120, the gluteal strap 118 and the crotch straps 114, 116. The tension
in these straps 106, 108, 110, 112, 114, 116, 118, 120, 206, 208, 210, 212 provides
moment that act against medial rotation of the legs of the wearer at the hip joints
(the two acetabulofemoral joints) and about sagittal axes passing through the hip
joints.
[0069] When a person is swimming, a "snaking effect" can occur due to medial/lateral rotation
of the legs at the hip joints. The constriction effect provided by the jammer 100
reduces or eliminates this snaking effect, improving the efficiency of a wearer's
stroke and potentially enables the wearer to swim faster.
[0070] Embodiments of the invention reduce the amount of pressure drag on the wearer by
reducing the cross-sectional area of water that the wearer is "swimming through".
This is achieved by restricting the medial/lateral rotation of the legs of the wearer
at the hip joints (i.e. the "snaking effect").
[0071] The curved nature of the first, second, third, fourth, fifth, sixth, seventh and
eighth longitudinal straps 106, 108, 110, 112, 206, 208, 210, 212 acts to distribute
the tension in the side panels 34, 38 over a larger area at the wearer's hips and
just above the wearer's knees, ensuring that the jammer is securely anchored at the
hips and just above the knees of the wearer and that the side panels 34, 38 are appropriately
tensioned.
[0072] It may be possible to increase the amount of tension in the first, second, third,
fourth, fifth, sixth, seventh and eighth longitudinal straps 106, 108, 110, 112, 206,
208, 210, 212, the inner leg strap(s) 120, the gluteal strap 118 and the crotch straps
114, 116 by stretching them, thereby increasing the constriction effect.
[0073] For example, the distance from the waist strap 4 to each of the lower extremities
31, 32 of the leg portions of the jammer 100 may be smaller than the distance from
the wearer's iliac crest or navel to the upper extremity of each of the wearer's knees.
When the jammer 100 is worn, it may be stretched such that it extends from a location
at or above the wearer's iliac crest or navel to a location at or just above the upper
extremity of each of the wearer's knees.
[0074] For instance, in this regard the jammer 100 may be shaped such that it extends from
the wearer's iliac crest/navel to the upper extremity of the wearer's knees when stretched
to between 110% and 130% of its original, unstretched length. In some embodiments,
the jammer 100 may shaped such that it fits in this way when stretched to between
110% and 120% of its original, unstretched length. In some further embodiments, the
jammer 100 may shaped such that it fits in this way when stretched to substantially
114% of its original, unstretched length.
[0075] In this example, the waist strap 4 is an elasticated waistband that extends around
the whole circumference of a wearer's waist. It may, for example, have an elastic
modulus in the range 100 N/m to 3000 N/m. In some embodiments, the waist strap 4 has
an elastic modulus of at least 300 N/m. In some further embodiments, the waist strap
has an elastic modulus of at least 700 N/m. In still further embodiments, the waist
strap has an elastic modulus of at least 1000 N/m.
[0076] Each of first, second, third, fourth, fifth, sixth, seventh and eighth longitudinal
straps 106, 108, 110, 112, 206, 208, 210, 212, the first and second crotch straps
114, 116, the gluteal strap 118, the inner leg strap(s) 120, and the first, second,
third, fourth lateral thigh straps 124, 126, 128, 130 might have an elastic modulus
in the range 100 N/m to 3000 N/m. In some embodiments, the straps 106, 108, 110, 112,
114, 116, 118, 124, 126, 128, 130, 206, 208, 210, 212 may each have an elastic modulus
of at least 300 N/m. In some further embodiments, the straps 106, 108, 110, 112, 114,
116, 118, 124, 126, 128, 130, 206, 208, 210, 212 may each have an elastic modulus
of at least 700 N/m.
[0077] Each of first, second, third, fourth, fifth, sixth, seventh and eighth longitudinal
straps 106, 108, 110, 112, 206, 208, 210, 212, the first and second crotch straps
114, 116, the gluteal strap 118, the inner leg strap(s) 120, and the first, second,
third, fourth lateral thigh straps 124, 126, 128, 130 might each have a width (for
joining adjacent panels) of 20 millimeters or less. In some embodiments, the straps
106, 108, 110, 112, 114, 116, 118, 124, 126, 128, 130, 206, 208, 210, 212 may each
have a width of 15 millimeters or less.
[0078] The jammer 100 may be compliant with rules set out by the Federation Internationale
de Natation Amateur (FINA). FINA rules set restrictions on the amount of seams that
can be provided in swimwear, state that straps/tapes may only be provided to join
elements of swimwear, and state that such straps/tapes may have a maximum width of
20 millimeters.
[0079] Those that are skilled in the art will appreciate that the arrangement of the seams
in the shell 80 of the jammer 100 has been chosen carefully to enable the straps 106,
108, 110, 112, 114, 116, 118, 124, 126, 128, 130, 206, 208, 210, 212 to be appropriately
positioned in order to achieve the constriction effect described above.
[0080] It will be appreciated by those skilled in the art that embodiments of the invention
are not limited to a jammer. By way of example, embodiments of the invention will
now be described in the context of first and second women's swimskins.
[0081] Figures 5A and 5B illustrate front and rear elevations of an external surface of
a shell 81 of swimwear, in the form of a first women's swimskin. The shell of the
swimskin is similar to the shell 80 of the jammer 100, except that it is instead also
shaped to cover the upper body of a woman. In this regard, the crotch panel 36 has
been replaced by a front body panel 136 and a rear body panel 66 has been added. The
first, second, third and fourth longitudinal seams 6, 8, 10, 12 extend beyond the
hip regions 1001, 1003 of the wearer and to underarm regions 1008, 1009 of the wearer.
[0082] Also, in the illustrated example, the first, second, third and fourth longitudinal
seams 6, 8, 10,12 are substantially linear, as shown in the illustration of an external
surface of the first side panel 34 of the shell 81 in fig. 5C.
[0083] Furthermore, the shell 81 of the first swimskin comprises a rear waist seam 64 that
extends laterally and provides a boundary between the rear body panel 66 and each
of the first upper rear panel 48 and the second upper rear panel 50.
[0084] Figures 6A and 6B illustrate front and rear elevations of an internal surface of
the shell 81 of the first swimskin. In figs 6A and 6B, the shell 81 has been turned
inside-out to show the internal surface. Fig. 6C illustrates the internal surface
of the first side panel 34.
[0085] Figs 3A and 3B illustrate front and rear elevations respectively of the internal
surface of the first swimskin 200 (that is, the first swimskin 200 in its inside-out
configuration) including the shell 81 and the lower body harness 5. In this example,
some of the straps in the lower body harness 5 also extend to the wearer's upper body.
[0086] It can be seen in figures 7A and 7B that the full circumference waist strap 4 that
was provided in the jammer 100 has been replaced by a half-circumference first waist
strap 164 that extends laterally at the rear of the wearer's waist. The first waist
strap 164 is positioned on and along the rear waist seam 64, on the internal surface
of the shell 81, and connects the rear body panel 66 to each of the first upper rear
panel 48 and the second upper rear panel 50. The first waist strap 164 may, for example,
be stitched, welded and/or adhered to the panels 48, 50, 66.
[0087] Figures 8A and 8B illustrate front and rear elevations of the external surface of
the first swimskin 200, respectively. Fig. 8C illustrates the external surface of
the first side panel 34.
[0088] The lower body harness 5 further comprises a second waist strap 264 that is positioned
on and along the rear waist seam 64, on the external surface of the shell 81, and
connects the rear body panel 66 to each of the first upper rear panel 48 and the second
upper rear panel 50. The second waist strap 264 may, for example, be stitched, welded
and/or adhered to the panels 48, 50, 66.
[0089] The first and second waist straps 164, 264, are therefore separated by the shell
81 of the first swimskin 200 at the rear waist seam 64. In some implementations, the
first and second waist straps 164, 264 may be attached to each other through the shell
81, for example, by stitching.
[0090] Each of the first and second waist straps 164, 264 might have an elastic modulus
in the range 100 N/m to 3000 N/m. In some embodiments, the straps 164, 264 may have
an elastic modulus of at least 300 N/m. In some further embodiments, the straps 164,
264 may each have an elastic modulus of at least 700 N/m.
[0091] Figures 9A-12B relate to a second swimskin 300 comprising a shell 82. The second
swimskin 300 differs from the first swimskin 200 in that the rear body panel 66 has
been replaced by first and second rear body panels 67, 68 that include an aperture
69.
[0092] Figures 9A and 9B illustrate front and rear elevations of an external surface of
the shell 82 of the second swimskin 300. Fig. 9C illustrates an external surface of
the first side panel 34 of the shell 82 of the second swimskin 300.
[0093] Figures 10A and 10B illustrate front and rear elevations of the internal surface
of the shell 82 of the second swimskin 300. That is, where the shell 82 of the second
swimskin 300 has been turned inside-out. Fig. 10C illustrates an internal surface
of the first side panel 34 of the shell 82 of the second swimskin 300.
[0094] Figures 11A and 11B illustrate front and rear elevations respectively of an internal
surface of the second swimskin 300. Fig. 11C illustrates an internal surface of the
first side panel 34 of the second swimskin 300.
[0095] Figs 12A and 12B illustrate front and rear elevations respectively of an external
surface of the second swimskin 300. Fig. 12C illustrates the external surface of the
first side panel 34 of the second swimskin 300.
[0096] Figs 13A, 13B and 13C illustrate front, rear and side elevations of an external surface
of swimwear in the form of a wetsuit 400 having first and second leg portions. The
wetsuit 400 may, for example, be a triathlon wetsuit.
[0097] The wetsuit 400 includes a waistband/waist strap 364, a first longitudinal strap/panel
206 and a second longitudinal strap/panel 208. The waist strap 364 is at least partially
positioned at or above the iliac crest of the greater pelvis of a wearer of the wetsuit
400. In this example, at the front of the wetsuit 400 the waist strap 364 extends
upwardly from a crotch region/panel 550 and is arranged to extend around the sides
and back of the waist of the wearer.
[0098] At the front of the wetsuit 400, as shown in Fig. 13A, the waist strap 364 is positioned
below a front body panel 136, and above the first and second longitudinal straps 206,
208 and first and second front thigh panels 640, 642.
[0099] At the rear of the wetsuit 400, as shown in Fig. 13B, the waist strap 364 is positioned
below a plurality of rear body panels 501-504 and a zipper 505, and above a gluteal
panel 601. The zipper 505 is used to (partially) open the wetsuit 400 in order to
allow a person to enter and don the wetsuit 400.
[0100] In this example, the waist strap 364 is directly attached to the front body panel
136, the crotch panel 550, the first and second longitudinal straps 206, 208, the
first and second front thigh panels 640, 642, the plurality of rear body panels 501-504
and the gluteal panel 601.
[0101] Unlike previous examples, in this example, the waist strap 364 is not positioned
on one or more seams. In this example, the periphery of the waist strap 364 provides
a junction between the waist strap 364 and adjacent panels/straps, at which a small
amount of overlap between the waist strap 364 and the adjacent panels/straps may be
present.
[0102] The first longitudinal strap 206 extends downwardly from a first hip region 1001
of the wearer to a first lateral thigh region 1002 of the wearer. It may, for example,
extend to a position at or around a first knee of the wearer. The second longitudinal
strap 208 extends downwardly from a second hip region 1003 of the wearer to a second
lateral thigh region 1004 of the wearer. It may, for example, extend to a position
at or around a second knee of the wearer.
[0103] In this example, the first longitudinal strap 206 is attached not only to the waist
strap 364 but also to the first front thigh panel 640 and at least one rear thigh/leg
panel 602, 603. Unlike previous examples, in this example, the first longitudinal
strap 206 is not positioned on one or more seams. The periphery of the first longitudinal
strap 206 provides a junction between the adjacent panels/straps, at which a small
amount of overlap between the first longitudinal strap 206 and the adjacent panels/straps
may be present.
[0104] The second longitudinal strap 208 is attached not only to the waist strap 364 but
also to the second front thigh panel 642 and at least one rear thigh/leg panel 604,
605. Unlike previous examples, in this example, the second longitudinal strap 208
is not positioned on one or more seams. The periphery of the second longitudinal strap
208 provides a junction between the adjacent panels/straps, at which a small amount
of overlap between the second longitudinal strap 208 and the adjacent panels/straps
may be present.
[0105] Each of the waist strap 364, the first longitudinal strap 206 and the second longitudinal
strap 208 has a higher elastic modulus than the adjacent panels 136, 550, 601-605,
640, 642. That is, each of the waist strap 364, the first longitudinal strap 206 and
the second longitudinal strap 208 is stiffer/less flexible than the adjacent panels
136, 550, 601-605, 640, 642. The waist strap 364, the first longitudinal strap 206
and the second longitudinal strap 208 may be stiffer/less flexible than any other
material that is used to form panels of the wetsuit 400.
[0106] In some embodiments, the elastic modulus of each of the waist strap 364, the first
longitudinal strap 206 and the second longitudinal strap 208 could, for example, be
10-40% greater than the elastic modulus of other panels of the wetsuit 400, such as
the adjacent panels 136, 550, 601-605, 640, 642.
[0107] The first longitudinal strap 206 and the second longitudinal strap 208 are made from
neoprene. For instance, the waist strap 364, and the adjacent panels 136, 550, 601-605,
640, 642 (along with other panels of the wetsuit 400) may be made from neoprene, but
the waist strap 364, the first longitudinal strap 206 and the second longitudinal
strap 208 may be made from a different (stiffer/less flexible) neoprene than the adjacent
panels 136, 550, 601-605, 640, 642.
[0108] For example, the waist strap 364, the first longitudinal strap 206 and the second
longitudinal strap 208 may be made from petroleum/oil based neoprene and the adjacent
panels 136, 550, 601-605, 640, 642 (and other panels of the wetsuit 400) may be made
from limestone based neoprene.
[0109] The waist strap 364 can be considered to be means for providing tension at or above
the iliac crest of the wearer. The zipper 505 (potentially along with some of the
back panels 501-504 of the wetsuit 400) can also be considered to be means for providing
tension at or above the iliac crest of the wearer. Another form of (elongate) back
fastener could be used instead of the zipper 505 in other examples.
[0110] Each of the waist strap 364, the first longitudinal strap 206 and the second longitudinal
strap 208 acts as a stiffening member. The first and second longitudinal straps 206,
208 are effectively elongate stiffening members that are arranged to extend down the
sides of the wearer's legs.
[0111] Collectively the waist strap 364, the first longitudinal strap 206 and the second
longitudinal strap 208 provide a similar effect to that described above in relation
to the jammer 100 and the swimskins 200, 300, in that they reduce or eliminate the
snaking effect that can occur due to medial/lateral rotation of the legs at the hip
joints, improving the efficiency of the wearer's stroke and potentially enabling the
wearer to swim faster.
[0112] Leg panels within the leg portions of the wetsuit 400, such as those designated with
the reference numerals 640, 642, 603 and 605 may perform the functionality of the
first and second gripper straps 60a, 60b described above by gripping to an area of
the wearer's leg just above the knee. In view of this, separate gripper straps 60a,
60b made from silicone are not necessary in this example.
[0113] Although embodiments of the present invention have been described in the preceding
paragraphs with reference to various examples, it should be appreciated that modifications
to the examples given can be made without departing from the scope of the invention
as claimed. For example, it will be appreciated by those skilled in the art that embodiments
of the invention can be applied to other items of swimwear that are not illustrated
in the appended figures. Such swimwear includes, but is not limited to, men's swimskins,
swimwear that extends below the knees of a wearer, wetsuits and the like. The shell
of such a wetsuit may, for example, be made from material that is not air and water
permeable, such as neoprene.
[0114] In a wetsuit, the tension that is provided at or above the iliac crest of a wearer
need not be provided by a waist strap or a drawstring. Instead, as explained above,
it could be provided by a substantially vertical zipper in the shell of a wetsuit
that is arranged to draw lateral portions either side of the zipper together to create
the tension.
[0115] It will also be appreciated by those skilled in the art that any straps that have
been described above as being on the inside of the shells 80, 81, 82 of the swimwear
100, 200, 300 could instead be on the external surface of the shells 80, 81, 82 and
vice versa. Furthermore, straps could be provided on both the internal surface of
the shells 80, 81, 82 and the external surface of the shells 80, 81, 82 along any
of the aforementioned seams.
[0116] Features described in the preceding description may be used in combinations other
than the combinations explicitly described.
[0117] Although functions have been described with reference to certain features, those
functions may be performable by other features whether described or not.
[0118] Although features have been described with reference to certain embodiments, those
features may also be present in other embodiments whether described or not.
