Best BJJ Rash Guards: How to Choose One for Training and Competition
Short answer: choose a close-fitting polyester/spandex rash guard with sublimated graphics and flat seams. For daily no-gi training our pick is the Kore V2 Short Sleeve (€42). For IBJJF no-gi events, wear the Ranked Performance V3 (€50 long sleeve, €48 short sleeve), which carries IBJJF-approved rank colours. Training three or more times a week? Keep two or three in rotation.
In no-gi your rash guard is the layer between your skin and the mat, and between you and your training partners. A good one guards against mat burn, moves sweat away so you do not slide out of position and gives light compression through hard rounds. A poor one rides up, pills or loses its print within months. This guide explains what to look for and compares every Kingz rash guard currently in stock on kingzeurope.com.
What to look for
Fabric. Polyester/spandex blends between 80/20 and 90/10 are the standard. More spandex gives more stretch and compression; more polyester gives more durability.
Sublimated graphics. Sublimation dyes the design into the fibres, so it cannot crack or peel the way a printed design can after repeated washing.
Flat seams. Flat seams lie against the skin, so they do not chafe or split when someone grips them.
Fit. It should sit like a second skin, long enough to stay tucked in, with no loose fabric to grab and no pressure on your breathing.
IBJJF rules. For adult IBJJF no-gi divisions the rash guard must be skin-tight, black, white or black and white, with at least 10% of your belt colour; a top that is entirely your belt colour is also allowed.

Our picks
For everyday training: Kore V2 Short Sleeve (€42)
The Kore V2 is the rash guard we built for daily rounds: 90/10 polyester/spandex, a snug athletic cut that stays in place and a price that makes two or three easy to justify. It comes in black, steel blue and olive green, sizes XS–XXL. It also works for MMA, where short sleeves stay cooler in striking rounds.
For IBJJF no-gi: Ranked Performance V3 (€50)
The Ranked Performance V3 puts your belt colour in the shoulder panels and mesh underarm inserts, so it meets IBJJF no-gi colour rules with a clean look. The 80/20 fabric holds its shape and the performance cut leaves the shoulders free. Long sleeve €50, short sleeve €48, in blue, purple, brown and black, sizes XS–4XL.
For women: Terra Women's (€45)
The Terra is cut on a women's pattern in 90/10 polyester/spandex with sublimated graphics, sizes XS–XL. Under the gi, the IBJJF asks women to wear a fitted stretch top, and the colour rules do not apply there, so any of our rash guards works. See the women's no-gi collection.
For kids: Kore V2 Youth (€45)
For children, choose something snug, easy to wash and comfortable enough to forget about. The Kore V2 Youth is 80/20 polyester/spandex in long (€45) or short sleeve (€40), youth sizes XS (4) to XL (12). The Ranked Youth (€40) adds rank-inspired colours in grey, yellow, orange and green. See all kids' rash guards.
How many do you need?
If you train no-gi more than twice a week, two or three. A rash guard should be washed after every session, and it will not always be dry by the next one. Rotating several means you never put on a damp top, and each one lasts longer.
Long or short sleeve?
Long sleeves give more protection from mat burn and skin contact, which is why most competitors wear them. Short sleeves stay cooler in a warm room and leave the arms freer. Many people own both. For a first rash guard, long sleeve is the safer choice.
Care
Wash cold after every session, inside out, and hang dry. Skip the tumble dryer and fabric softener: heat and softener break down spandex. Size by body weight using the chart on each product page; if the fit is wrong, our 60-Day Perfect Fit Guarantee covers an exchange of unworn items. Standard shipping from our Polish distribution centre is free over €120.
Frequently asked questions
What is the best rash guard for no-gi BJJ?
A snug polyester/spandex rash guard with sublimated graphics. Our everyday pick is the Kore V2 Short Sleeve (€42); for IBJJF no-gi events, the Ranked Performance V3 (€50 long sleeve) with IBJJF-approved rank colours.
Are Kingz rash guards IBJJF legal?
The Ranked Performance V3 is made in IBJJF-approved rank colours (blue, purple, brown, black). Training designs such as the Kore V2 are for the academy rather than IBJJF no-gi divisions. Always check the current rules of your event.
Which rash guard works for both MMA and BJJ?
A snug short sleeve with no loose fabric, such as the Kore V2 Short Sleeve (€42). If you also compete under IBJJF no-gi rules, add a ranked rash guard for tournament day.
How should a rash guard fit?
Like a second skin: no loose fabric to grab, long enough to stay tucked in, and no pressure on your breathing. Size by body weight using the chart on each product page.
How do I make a rash guard last?
Wash it cold after every session, hang it to dry, skip the dryer and fabric softener, and rotate two or three so no single top is worn and washed every day.
