SWAX LAX lacrosse training balls are the first and only patented soft lacrosse ball that are the same size and weight as a regulation ball. They don’t roll, bounce, or rebound, making for a more productive practice, both indoors (won't harm gym floors) and outdoors (including tight spaces). They're perfect for at-home practices. Don't be fooled by imitation balls! The SWAX LAX practice ball was developed by a longtime lacrosse coach and has been field tested by boys and girls in kindergarten through men’s and women’s college lacrosse teams. SWAX LAX in an official training partner of US Lacrosse.
