BJJ Rash Guards for No-Gi Jiu-Jitsu

Price isn’t the whole story. What matters is stretch fabric, seams that stay put, and a fit that holds. Ours are polyester and spandex with flatlock stitching, and the products on this page carry ratings of 4.8 to 5.0. A pack of 3 brings the cost per shirt down further. 

When picking a rash guard, make sure to pick the right size based on your gender, weight, and height. Rash guards can come in the following sizes: smal, medium, large, extra large, and 2x large. Depending on whether you are a man, woman, or child, you will need to check a sizing chart for your specific demographic. Each size group corresponds with a certain height and weight range. If you are having difficulty finding a size that matches both your height and weight, use your weight as the determining factor.

Snug, not squeezing. If it bunches or rides up when you lie flat, it’s too big. If it pulls at your shoulders or limits your arms, go up a size. 

BJJ rash guard colors do not represent your current rank or level of experience like BJJ belts. The different colors BJJ rash guards come in give fighters a variety of styles to choose from. Depending on the BJJ location you train at, theyre may be some or no restrictions on which colors you can wear. At official tournaments, you are only allowed to wear black, white, or blue rash guards.

When washing a BJJ rash guard, make sure to set the washer to a low cycle setting. Also, set the temperature of the water to cool to prevent the rash guards from shrinking. Make sure to only use mild detergent. Soaps or fabric softener could cause the quality of the fabric to degrade. High heat can cause the fabric to lose their softness. After the rash guards are done washing, hang or air dry them rather than put them in a dryer.

It keeps your skin off the mat and off your training partners. That means less mat burn and chafing, and a top you can wash after every class. 

Most gyms don’t require one, but almost everyone wears one. Some competitions do require it.

In training, yes. In IBJJF competition, men can’t wear one under the gi jacket, so check your event’s rules.

Don’t leave it balled up in your gym bag. Wash it right after class in cold water, skip the fabric softener, and hang it to dry. Heat and softener break down stretch fabric over time.
