BJJ RASHGUARDS

BJJ Rash Guards – Essential No Gi & Under Gi Training Gear

A good rash guard is one of the most important pieces of kit for any grappler. Whether you’re rolling no gi, wearing one under your BJJ gi, or stepping into an MMA bout, a rash guard protects your skin from mat burns and abrasions, reduces the spread of skin infections, and keeps you comfortable through hard training sessions. Every rash guard at Valor Fightwear is built to handle the demands of real grappling — reinforced stitching, performance stretch fabric, and designs that don’t fade.

Our Rash Guard Range

We stock men’s, women’s and kids’ rash guards in both short sleeve and long sleeve cuts. Our range runs from clean, understated training basics through to bold statement designs — including the Geometric series, the Classic mesh range, and the Neon Warfare collection for grapplers who want to stand out on the mats. All built to the same standard: tough, stretchy, and made to last.

Short Sleeve vs Long Sleeve

Short sleeve rash guards give more freedom of movement and are popular for no gi training in warmer conditions. Long sleeve offers more coverage and skin protection — preferred by many BJJ practitioners for full no gi sessions and under-gi wear. If you’re unsure, long sleeve is the more versatile choice for BJJ.

Rash Guard FAQ

Do I need a rash guard for BJJ?

Yes — for no gi training it’s essential. For gi training, wearing one under your jacket protects your skin, wicks sweat, and is required at many competitions.

What size should I order?

Our rash guards are sized in standard UK sizes. Check the size guide on each product page, or email us your height and build and we’ll recommend the right fit.

How do I wash a rash guard?

Wash cold and hang dry. Avoid fabric softener, which breaks down stretch fibres, and never tumble dry on high heat.
