No. Lacrosse players can only place tape or a grip material at the base of the stick to help them hold it tighter. You cannot place extra material at the top of the stick near the head. You cannot alter the composition of the stick, or shave down or bend the material to create more flexibility or reduce the weight of the stick. Additionally, a hollow men’s lacrosse stick must have a cap on the end that’s made specifically for lacrosse sticks.
