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.

    Great rash guard and shorts

    Been training in the shorts for over a year and still as solid as the day i got them. Rash guard is long so it doesn't ride up during rolls. Highly recommend both!

    Bjj gold

    I got a gi, rash guard, and shorts. The shorts and gi are amazing. The rash guard is a 2x and it fits very small. I fit in most other 2x rash guards. The gi is so nice and the shorts are so comfortable. Top notch gear I will for sure buy more gear from BJJ Gold.
