Frequently Asked Questions

What is the best rash guard for no-gi BJJ?
For everyday training, the Kore V2: durable polyester–spandex with a snug athletic fit. For IBJJF no-gi competition, the Ranked Performance V3, which is 80% polyester / 20% spandex with IBJJF-approved rank colors. Read our full rash guard guide.

Which Kingz rash guards are IBJJF legal?
The Ranked Performance V3 and V2 are made with IBJJF-approved rank colors. For adult IBJJF no-gi, your rash guard must be skin-tight and black, white, or black and white with at least 10% of your belt color. Our graphic designs are made for training.

What size rash guard should I get?
Size by body weight. On our Ranked Performance rash guards, XS is 100–120 lbs, S 120–145, M 145–170, L 170–200, XL 200–225 and XXL 225–260. A rash guard should fit snug like a second skin, and each product page lists its own range.

Long sleeve or short sleeve?
Long sleeve gives more protection against mat burn and is what most no-gi regulars and competitors wear. Short sleeve runs cooler and frees your arms. If you're buying your first rash guard, go long sleeve.

How do I make my rash guard last?
Wash it after every session, in cold water, and hang it to dry. Keep two or three in rotation so no single rash guard is washed and worn every day. Most of our rash guards are 80% polyester / 20% spandex with sublimated graphics that won't crack or peel.

Can I wear a rash guard under my gi?
For training, yes. Many people do, for skin protection and to keep the gi drier. In IBJJF men's gi divisions, shirts under the gi aren't allowed, so check your event's rules before competing.
