Abstract: An article of headwear includes a crown portion dimensioned to cover a portion of a forehead of a wearer when the article of headwear is worn by the wearer, and a brim that extends transversely from the crown. The crown and brim are formed of a single unitary molded body including an upper fabric layer, a lower fabric layer that faces toward the head of the wearer, and an intermediate layer disposed between the upper fabric layer and the lower fabric layer, and each of the upper fabric layer, the lower fabric layer and the intermediate layer continuously extends between the crown and the brim. A transition angle is defined at a transition between the brim and the crown, wherein the transition angle is obtuse.

Abstract: A strap system designed to cushion applied tensile force is disclosed. The strap system includes an expandable member configured to deform under the applied tension force and a restriction member that influences the deformation pattern of the expandable member. For example, the restriction member may limit the amount of stretch experienced by the expandable member. The strap system may be incorporated as shoulder straps into a backpack to reduce pressure to the back and shoulders typically experienced by a wearer.

Abstract: A bag is disclosed herein in the form of a backpack. The backpack comprises a bag portion and at least one shoulder strap coupled to the bag portion. The least one shoulder strap includes an elastic upper broad strap portion connected to an inelastic lower broad strap portion. The upper broad strap portion defines a corrugated structure having a plurality of parallel ridges and furrows. The upper broad strap portion is also configured to stretch between a relaxed position and a stretched lockout position. A lockout webbing is coupled to the upper broad strap portion at a plurality of connection locations along the upper broad strap portion. Loops in the lockout webbing are formed between the connection locations when the upper broad strap portion is in the relaxed position. The lockout webbing is fully extended when the upper broad strap portion is in the stretched lockout position.

Abstract: A backpack includes a main body including a front side and a rear side, a pair of shoulder straps extending from the rear side, where at least one of the shoulder straps includes a rail disposed on a surface of the shoulder strap that opposes the rear side, and a clip that secures to the rail of the shoulder strap. The clip includes a rail securing member that secures to the rail, and an accessory engagement member that supports an item by the backpack via the clip when the backpack is worn by a user.

Abstract: An article of headwear includes a crown portion dimensioned to cover a portion of a forehead of a wearer when the article of headwear is worn by the wearer, and a brim that extends transversely from the crown. The crown and brim are formed of a single unitary molded body including an upper fabric layer, a lower fabric layer that faces toward the head of the wearer, and an intermediate layer disposed between the upper fabric layer and the lower fabric layer, and each of the upper fabric layer, the lower fabric layer and the intermediate layer continuously extends between the crown and the brim. A transition angle is defined at a transition between the brim and the crown, wherein the transition angle is obtuse.

Abstract: Bite-actuated mouthpieces and drink vessels including bite-actuated mouthpieces are disclosed. Bite-actuated mouthpieces comprise a body comprising a dispensing wall, one or more sidewalls extending from the dispensing wall that with the dispensing wall define an internal volume, and an inlet to the internal volume. The self-sealing exit is biased toward a closed configuration and is configured to be selectively reconfigured from the closed configuration to an open configuration responsive to user-applied compressive forces to opposing bite regions. The dispensing wall has a dispensing face opposite the internal volume, and in some examples, the dispensing face is concave.

Abstract: A backpack includes a main body including a front side and a rear side, a pair of shoulder straps, each shoulder strap extending from a first fixed end at an upper portion of the rear side to a second free end, and a shoulder strap leveling structure coupled with each of the shoulder straps. Each shoulder strap leveling structure is coupled with a corresponding shoulder strap and includes a slip lock member disposed along a portion of the corresponding shoulder strap, and a bulk strap including a first end coupled with the rear side of the backpack and a second free end that is moved through a slot of the slip lock member. Each bulk strap also includes a plurality of markings arranged along a length dimension of the bulk strap that are visible through a window of the slip lock member.

Abstract: A backpack includes a bag portion and at least one shoulder strap coupled to the bag portion. The at least one shoulder strap includes a non-elastic first strap portion coupled to an elastic second strap portion. The second strap portion is auxetic or near auxetic such that a Poisson's ratio of the second strap portion is less than a Poisson's ratio of the first strap portion.

Abstract: A face guard is disclosed herein. The face guard is configured for a human user having a face with a mouth and nose. The face guard includes a mouthpiece configured for retention in the mouth of the human user. The face guard also includes a face mask coupled to the mouthpiece, wherein the face mask configured to cover the mouth and nose of the human user.

Abstract: A sports ball comprises a bladder and a contouring layer surrounding the bladder. The contouring layer includes at least one panel defining a repeating pattern of perforations configured to lower a Poisson's ratio of the contouring layer. Each of said perforations defines a reentrant shape and a constant cross-sectional width in a radial direction of the ball.

Abstract: A sports accessory is provided to be worn by a user during a sport activity. The accessory includes a flexure system. The flexure system includes a support structure including a plurality of intersecting grooves disposed along a surface of the support structure, where a plurality of segments are defined along the surface of the support structure between the intersecting grooves such that the support structure is configured to flex along the grooves with segments moving in relation to other segments during use of the sports accessory.

Abstract: Bite-actuated mouthpieces and drink vessels including bite-actuated mouthpieces are disclosed.
