The Anthem Athletics Resilience fight shorts is a perfect gift for a no-gi BJJ grappler. They are made to be tear resistant and hard to move once on. The waistband has velcro and a drawstring on the inside of the shorts preventing the string from being caught while grappling. Crotch area has stretch material and side slits allows someone to move more freely. The ability to move freely will allow someone to get into the positions they need to be in.
See sizing chart to ensure proper fit as fight shorts tend to run more tight than regular shorts or pants.
