The stick is the main equipment in lacrosse. It is used to move the ball up and down the field to attack as well as defend against the opponent from doing that.
The game rule permits one and two-handed stick checks, as well as closed handed stick-on-body check. Therefore, if you have the ball, you are prone to slashing and hacking from defenders and midfielders.
They aim to knock the ball loose by hitting your glove or stick, but in all this, it is your body that takes the brunt. It is therefore essential you are protected with the best lacrosse arm guards, one that does not impede shot, catch, throw and mobility.
