Our Shorts go above & beyond the normal remake of a surf trunks that our competitors use. All our fight shorts use the highest quality material that is a two-way mechanical stretch material with triple stitching and bar tacked reinforced tear zones. Our waist bands are reinforced and feature an inside corded drawstring that will not come untied in the middle of a fight. Our triple closure features the hook and loop closure on the outside so you don't get mat burn from your shorts.
