Abstract

A wetsuit for aquatic activities may include a wetsuit material having a first surface and an opposite second surface. The wetsuit comprises one or more sipes on the first surface that extend from an upper portion of a chest region of the wetsuit to a lateral portion of the chest region of the wetsuit.

First claim

What is claimed is:

1. A wetsuit for aquatic activities, the wetsuit comprising:
a base layer having a first surface and an opposite second surface;
a first backing layer having a first surface and an opposite second surface, the second surface of the first backing layer continuously secured to the first surface of the base layer, the first surface of the first backing layer forming an exterior surface of the wetsuit;
a second backing layer secured to the second surface of the base layer and forming at least a portion of an interior surface of the wetsuit; and
at least one sipe linearly extending from the first surface of the first backing layer comprising the exterior surface of the wetsuit through the first backing layer and into the base layer, the at least one sipe extending from an upper portion of a chest region of the wetsuit to a lateral portion of the chest region of the wetsuit.

2. The wetsuit of claim 1 , wherein the at least one sipe is curved.

3. The wetsuit of claim 1 , wherein a depth of the at least one sipe is approximately 60 percent of the total thickness of the wetsuit between the exterior surface and the interior surface.

4. The wetsuit of claim 1 , wherein the at least one sipe is a first sipe and the wetsuit comprises a second sipe, the first sipe being spaced from the second sipe and substantially parallel to the second sipe.

5. The wetsuit of claim 4 , wherein the wetsuit comprises:
a first set of sipes including at least the first sipe and the second sipe; and
a second set of sipes including at least a third sipe and a fourth sipe spaced from the third sipe and substantially parallel to the third sipe.

6. The wetsuit of claim 5 , wherein the first set of sipes extends from the upper portion of the chest region to a right lateral portion of the chest region of the wetsuit, and the second set of sipes extends from the upper portion of the chest region to a left lateral portion of the chest region.

7. The wetsuit of claim 1 , wherein the at least one sipe comprises a first end in the upper portion of the chest region and extends from the first end in a generally inferior direction and curves toward a second end in the lateral portion of the chest region.

8. The wetsuit of claim 1 , wherein the at least one sipe is formed by a slit cut a predetermined depth into the wetsuit while in a substantially planar arrangement, the slit opening to form a sipe having a substantially v-shaped cross-sectional shape when the wetsuit is worn with the portion of the wetsuit including the slit located over a convex body surface of a wearer.

9. A wetsuit for aquatic activities, the wetsuit comprising:
a base layer having a first surface and an opposite second surface;
a first backing layer having a first surface and an opposite second surface, the second surface of the first backing layer continuously secured to the first surface of the base layer, the first surface of the first backing layer forming an exterior surface of the wetsuit;
a second backing layer secured to the second surface of the base layer and forming at least a portion of an interior surface of the wetsuit; and
a plurality of sipes, each of the plurality of sipes linearly extending from the first surface of the first backing layer comprising the exterior surface of the wetsuit through the first backing layer and into the base layer, each sipe of the plurality of sipes having a superior end positioned at an upper portion of a chest region of the wetsuit, an inferior end positioned at a lateral portion of the chest region of the wetsuit, and an intervening portion disposed between the superior end and the inferior end.

10. The wetsuit of claim 9 , wherein the intervening portion of the each sipe is curved.

11. The wetsuit of claim 9 , wherein the each sipe of the plurality of sipes is spaced apart from an adjacent sipe.

12. The wetsuit of claim 11 , wherein adjacent sipes are substantially parallel to each other.

13. The wetsuit of claim 11 , wherein adjacent sipes are non-parallel to each other.

14. The wetsuit of claim 11 , wherein a first space between a first pair of adjacent sipes is different than a second space between a second pair of adjacent sipes, and wherein the first pair of adjacent sipes is parallel to the second pair of adjacent sipes.

15. A wetsuit for aquatic activities, the wetsuit comprising:
a base layer having a first surface and an opposite second surface;
a first backing layer having a first surface and an opposite second surface, the second surface of the first backing layer continuously secured to the first surface of the base layer, the second surface of the first backing layer forming an exterior surface of the wetsuit;
a second backing layer secured to the second surface of the base layer and forming at least a portion of an interior surface of the wetsuit;
a first set of sipes linearly extending from the first surface of the first backing layer comprising the exterior surface of the wetsuit through the first backing layer and into the base layer, the first set of sipes positioned on a first side of a chest region of the wetsuit; and
a second set of sipes linearly extending from the first surface of the first backing layer comprising the exterior surface of the wetsuit through the first backing layer and into the base layer, the second set of sipes positioned on a second side of the chest region of the wetsuit.

16. The wetsuit of claim 15 , wherein the first side is a left side of the chest region of the wetsuit, and wherein the second side is a right side of the chest region of the wetsuit.

17. The wetsuit of claim 15 , wherein each sipe in the first set of sipes extends from an upper portion of the chest region of the wetsuit to a lateral portion of the chest region.

18. The wetsuit of claim 15 , wherein each sipe in the second set of sipes extends from an upper portion of the chest region of the wetsuit to a lateral portion of the chest region.

19. The wetsuit of claim 1 , wherein the first backing layer is continuously secured to the first surface of the base layer in the chest region of the wetsuit and forms an exterior surface of the wetsuit in the chest region of the wetsuit.
