No-Gi BJJ Training: What to Wear and Why It Matters
No-gi BJJ removes the gi's grips, but it doesn't remove the demands on your gear — if anything, it raises them. Skin-on-skin and rashguard-on-rashguard contact means slick, sweat-heavy grappling, so your rashguard needs a snug compression fit that won't ride up during scrambles or get grabbed like a loose t-shirt would.
Flatlock seams are the detail to check for. Standard stitching can rub and irritate skin during long grappling exchanges, especially around the underarms and shoulders where friction is constant in guard passing and takedowns. Flatlock construction lies flatter against the skin and holds up better under repeated grip pressure.
Shorts matter too. No-gi shorts need a fitted, MMA-style cut rather than a wide-leg Muay Thai cut — loose fabric gives training partners something to grab, which works against you in a no-gi ruleset where grips are limited to the body and clothing itself.
Durability is the last piece. No-gi training is high-friction by nature, so look for high-stretch, sweat-wicking fabric that's been genuinely tested in live rolling, not just designed to look good in photos.
