A fitness device is provided, the fitness device comprising: an elastomeric member having an interior cavity, the elastomeric member comprising a cylindrical portion extending between a first hemispherical endcap and a second hemispherical endcap, wherein a surface of the elastomeric member defines an aperture positioned between the interior cavity and an exterior of the elastomeric member; and a structured surface positioned on the surface of the elastomeric member over the aperture, the structured surface extending into the interior cavity of the elastomeric member.

A sports ball outer casing comprising a ball-shape frame (4) defining a plurality of openings (6, 6a, 6b) and a plurality of panels (8), each panel being secured to the frame to cover a respective one of said plurality of openings. In this construction the frame provides a ‘skeleton’-like structure that can follow what would be the seam lines between panels in a conventional ball casing.

One or more aspects of the present disclosure are directed to bladders that incorporate a multi-layer optical film that impart a structural color to the bladder. The present disclosure is also directed to articles including the bladders having a multi-layer optical film, and methods for making articles and bladders having a multi-layer optical film.

The sports ball (410) has an inner layer (416) and an outer panel (414). The inner layer (416) is secured to the outer panel (414) and several inner layers (416) and outer panels (414) are sewn together to form the sports ball (410). A strip (440) is positioned between the inner layer (416) and outer panel (414) under a white stripe (448) to raise the white stripe (448) on the sports ball (410) above the surrounding outer surface of the sports ball (410) to enhance grip. The sports ball (410) can be a football (412). A line of thread (424) can be stitched between the inner layer (416) and outer panel (414) on either side of the stripe (448) to enhance the shape retention of the sports ball (410), enhance grip and help keep the strip (440) in place. In a modification, a strip (480) is positioned between the inner layer (416) and outer panel (414) except under the white stripe (448) to form a void under the stripe (448) and enhance grip.

A DPS (dual pressure system) sport ball incorporating a special, environment friendly casing that forms an exterior surface of the ball, which is bonded to a multiple lining layers to form a laminated sheet. The laminated sheet is sized, printed, and cut out into specifically designed panels using highly optimized and automated specifically developed machines. The panel cut outs are stitched together using a special stitching machine and a specific, compatible bladder is incorporated in the ball. The partially machine stitched ball is then finally closed by manual stitching and the seams are protected with a special adhesive. Resultantly, due to unique construction materials, their unique arrangement, innovative technology, and highly automated manufacturing processes, the DPS sport ball has advantageous durability, playability, controllability and excellent flight characteristics. The DPS sport ball qualifies under the international standards of match/professional balls at a very competitive price.

An enclosure assembly is configured to enclose a game ball having an outer game-ball relief feature.

A sport ball may include a casing and a bladder located within the casing. The casing may include a plurality of panel elements joined to each other with welds, and portions of the panel elements that include the welds may project toward an interior of the ball. A method of manufacturing a sport ball may include providing a plurality of casing elements that include a thermoplastic polymer material. Edges of the casing elements are welded to each other to join the casing elements. The casing elements may then be turned inside-out through an aperture formed by at least one of the casing elements, and the aperture may be sealed.
