A removable cover for a lacrosse stick of the type having an elongated hollow shaft having an outer surface and an inner surface and an interior channel extending therethrough and a free end portion with an open end which serves as a handle portion of said lacrosse stick. The cover includes an end cap configured and dimensioned to be removably mountable in a friction fit manner on the free end portion of the hollow shaft. The end cap has a head portion and an elongated, resilient hollow body portion attached to said head portion and insertable into the open end of the free end portion of the hollow shaft. A flexible, resilient, membrane-like, tubular sheath is removably mountable on the outer surface of the free end portion of the hollow shaft and is movable thereon between a furled position in which the sheath is rolled longitudinally on and along said free end portion of the hollow shaft onto itself to form a rolled-up tubular sheath disposed adjacent to the end cap, and an unfurled position, in which the rolled-up tubular sheath is unrolled longitudinally on and along the outer surface of the free end portion of the hollow shaft. The tubular sheath is dimensioned to create a friction fit when mounted on the hollow shaft. The sheath has a flap which is inserted into the open end and interior channel of the shaft. Both the sheath and the flap are removably secured to the end cap.

This disclosure describes a launcher and a projectile for fetch games with pets. The launcher, in certain implementations, may be used to pick up and launch the projectile that has a core to engage with a head of the launcher. Same size cores may be used in projectiles of different sizes, appearances, shapes, and materials (for different pets) such that a common launcher can be used.

A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).

A sport exercise device; for use with a sport stick, the sport stick having a head and a shaft. The device comprises a face, edge and attachment means. In one approach, the edge is adapted and arranged to surround the stick's head. The attachment means allows attachment of the device's face to hold an independently provided weight with respect to the head. The attachment means may allow attachment of the device's face to close the stick's net sufficient to prevent out-passage of a ball within the net.

A hockey stick or other sporting implement designed to enhance its use, performance and/or manufacturing, including, for example, by being lightweight, having improved strength, flex, stiffness, impact resistance and/or other properties, reducing scrap waste during its construction, and/or enhancing other aspects of the hockey stick or other sporting implement. For instance, in some embodiments, the hockey stick or other sporting implement may include a structure that is open, such as by being latticed (e.g., trussed), and/or made by additive manufacturing, selective material positioning, etc.

A lacrosse head spacer includes a front surface, left and right side surfaces attached at a left and right edges of the front surface, and a curved back surface extending between the left and right side surfaces. A width of the lacrosse head spacer measured perpendicularly from the left side surface to the right side surface is larger than a minimum width dimension specified by NCAA rules for lacrosse heads such that when the lacrosse head spacer is inserted between sidewalls of a lacrosse head, the lacrosse head spacer maintains the sidewalls apart from each other at a distance larger than the minimum width dimension specified by NCAA rules for lacrosse heads.
