The crosse (lacrosse stick) is divided into two parts, the shaft and the head. The shaft can be made of a variety of materials such as wood, aluminum and composite materials depending on what position the player prefers. Women's lacrosse rules mandate that only composite and aluminum shafts can be used, due to accidental checks and hitting that can happen during the duration of the games. The top of the stick is where the head joins the shaft to make the whole stick. The head is made of compact plastic where the mesh, sidewall and pocket form.
