The best box lacrosse shoulder pads in the game are the Fatboy Pro's from Warrior. Beefy protection that comes all the way down over the biceps. Wide front and back plates that have low definition rib padding so you can strap on additional rib or kidney pads. These are adjustable with nice wide, high quality straps. One of the coolest features is that you can remove the bicep pads and shoulder caps to use as a shoulder pad liner for when you are playing field lacrosse. The Fatboys also feature good collarbone width coverage. This is the heaviest grade box lacrosse shoulder pad available from Warrior!
