Buying guide
How to choose a rash guard
A rash guard has three jobs: stay put, survive grips, and, if you compete, match the IBJJF's colour rule. The fabric blend tells you most of what you need: rash guard makers suggest roughly 80/20 to 88/12 polyester to spandex, where more spandex means more stretch and more polyester means more durability.
Look for flatlock seams, which lie flat and are less likely to split than cheaper overlock seams. A gel or silicone waistband stops the hem riding up.
What to check
- Blend: around 80/20 to 88/12 polyester to spandex
- Seams: flatlock over overlock
- Waist: a gel band stops it riding up
- IBJJF no-gi: black, white or black and white with at least 10% belt colour, or all belt colour
Questions
Quick answers
What rash guard colours are IBJJF legal?
Black, white, or black and white with at least 10% of your belt colour, or a top that's 100% your belt colour. It must be skin-tight and long enough to reach the waistband of your shorts.
Should a rash guard be tight?
Yes. A rash guard should be skin-tight, and the IBJJF requires an elastic, skin-tight top for no-gi competition.
Long sleeve or short sleeve?
Both are legal for IBJJF no-gi. Long sleeves protect more skin from mat burn; short sleeves run cooler. Most people own one of each.
