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.

We proudly back all of our products by the Gold BJJ Guarantee.

If for any reason you're not thrilled with your purchase, we'll replace or refund your order no-questions-asked.

    So far, so good!

    I’m 5’9” and 185-190 lbs. Normally wear Large t-shirts. I thought I’d add a legit rash guard in the rotation from the Walmart compression shirt, so I bought the XL short sleeve rash guard. Just trained wearing the new gear for the first time tonight and they felt very comfortable. The shirt felt a little tight, but not uncomfortably so. The next size up might have been a little loose for my preference, but probably still acceptable. I’ve trained in Gold gis since the beginning and love them, and so far the nogi gear has impressed me!

    Returning customer

    Great customer service and great quality but sizes run very small. I will have to order another that’s 2 sizes above my normal size.
