Pair with our Fight Shorts and a base layer of Spats or Compression Shorts for the ultimate No-Gi uniform.

Unrivaled Comfort

We use buttery smooth flatlock stitching that doesn't itch and irritate.

Slightly extended cut means that your rash guard won't ride up while you roll.

Ventilated mesh armpit vents allow you to get through the toughest training rounds without overheating.

Built to Last

Sublimated graphics won't fade or peel as you roll or wash your rash guard.

Backed by the Gold BJJ Guarantee: if you don't love your Foundation Rashguard, let us know and we'll replace or refund your order.

IBJJF Legal

Competition rules require that you wear a rash guard with at least 10% of your belt rank.

Don't get DQ'd for wearing an illegal uniform. Our Foundation rash guard has been specifically designed to meet all Jiu Jitsu tournament requirements.

    Way too tight

    I weigh 170 i usually wear a medium but I went with a large just to be safe. It was way too tight i could bare get it on, even smaller than my medium rash guards. Disappointing

    Love the gear!

    I ordered the white out short sleeve rash guard and shorts and love them. Amazing quality and they look fantastic. This is not my first purchase from Gold BJJ and it will definitely not be my last. Love supporting this company!
