Long Sleeve or Short Sleeve?

Long sleeve: covers your arms to the wrist, so you get more protection from mat burn and a bit more grip when everyone is sweaty. It’s also the usual pick under a gi.
Short sleeve: runs cooler and leaves your arms free. A good fit for no-gi in warm rooms.

Not sure? Get one of each. You’ll end up using both.

Getting the Size Right

Go with the size where the two meet.
Between sizes? Take the one that doesn’t pull at your shoulders.

It should feel snug, like a second skin, but you still need to breathe deeply and reach overhead.

What’s in It

The stretch comes from a polyester and spandex blend that moves with you and wicks sweat. Flatlock seams sit flat against your skin, so nothing rubs, and they hold up through a lot of washes.

Before You Compete

IBJJF no-gi events want black, white or black and white with your rank color showing. Other events are often looser. Check your event’s rules first, and see our guide to IBJJF no-gi uniform requirements.

Frequently Asked Questions

Are rash guards worth it for BJJ?

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.

How do I choose a BJJ rash guard?

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.

Should rash guard be tight or loose?

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.

Does rash guard color matter in BJJ?

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.

How do you get the smell out of a BJJ rash guard?

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.

What does a rash guard actually do?

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.

Do I need a rash guard for no-gi?

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

Can I wear a rash guard under my gi?

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

How do I stop my rash guard from smelling?

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.
