Abstract: Lacrosse heads are provided that include a polymer and graphene. The graphene increases the durability of the lacrosse heads. Also provided is equipment for other contact sports that include graphene to increase durability.

Abstract: 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.

Abstract: Lacrosse heads are provided that include a polymer and graphene. The graphene increases the durability of the lacrosse heads, while having limited impact on the stiffness and flexibility of the lacrosse heads. Also provided is equipment for other contact sports that include graphene to increase durability.

Abstract: A frame of a lacrosse head includes a ball stop, a scoop, a left sidewall, and a right sidewall. Each of the left and right sidewalls includes a top rail, a bottom rail, a first cross-strut extending between the top and bottom rails thereof, and a second cross-strut extending between the top and bottom rails thereof. The second cross-struts are disposed closer to the ball stop than the first cross-struts. The second cross-strut of the left sidewall is longer than the first cross-strut of the left sidewall and extends from the top rail to the bottom rail in the direction of the scoop to the ball stop. The second cross-strut of the right sidewall is longer than the first cross-strut of the right sidewall and extends from the bottom rail to the top rail in the direction of the scoop to the ball stop.
