Best BJJ Rash Guard Guide
The rash guard is essential for no-gi training. Learn what to look for, which brands dominate, and how to care for your rash guard.
Why Rash Guards Matter in BJJ
Rash guards protect your skin from mat burns, reduce direct skin contact with training partners, and regulate temperature. In no-gi training, a quality rash guard stays in place during scrambles without bunching. The compression fit also provides mild joint support. Long-sleeve rash guards provide more coverage; short-sleeve versions are cooler for hot gyms.
Materials and Fit
Quality rash guards use compression-grade spandex blends — typically 85% polyester, 15% spandex or similar. Flat-lock stitching prevents chafing. The fabric should feel tight when worn but should not restrict breathing or movement. Board shorts and spats (compression tights) are the standard bottom options for no-gi training.
Top Rash Guard Brands
Hayabusa, Tatami, Scramble, Kingz, and Hyperfly produce quality rash guards at various price points. Custom-print shops allow teams to create branded rash guards. For competition, verify that your organization allows the specific colors and designs you want to wear.
