BJJ Rash Guards

In BJJ, your top works harder than in almost any other combat sport. You spend much of the match on your back, playing guard; your partner’s jacket rubs against your arms and their grips pull at the fabric. A Brazilian jiu-jitsu rash guard stays close to the body, protects your skin from mat burn and stays in place during guard passes. Under a gi, it replaces a t-shirt that twists and bunches; worn alone, it becomes your no-gi uniform.

For gi training, choose long sleeves: they cover the forearm where the jacket scrapes the skin and slide under the gi without creasing. At the gym, any color works under the jacket; in competition, check the rules, as some events prohibit men from wearing a top under the gi. In no gi, both cuts work and color matters: at IBJJF tournaments, use a black, white or black-and-white base, with at least 10 % in your belt color. If you train both formats, a long-sleeve design with a dark base works everywhere. Find the 5 key criteria in our BJJ rash guard guide.

Every design covers the whole back and wraps around the sides and sleeves, with no empty space.

In BJJ with the gi, choose long sleeves: they protect the arms from jacket friction and don't ride up during guard passes. In no-gi and grappling, both cuts work; short sleeves leave the shoulders freer. In MMA and wrestling, short sleeves are the most common choice.

• Long sleeve, from $65BJJ in the gi, long sessions. 84% polyester, 16% elastane, sizes XS to 3XL.
• Short sleeve, from $65No-gi, grappling, MMA, wrestling. 88% recycled polyester, 12% elastane, sizes 2XS to 6XL.

The 2 cuts don't fit the same: in long sleeves, size down 1 from your usual size; in short sleeves, your usual size, or size up between two sizes. Measure your chest and check our size guide.

230 g/m², 4-way stretch, with flat seams: nothing rubs or gives out mid-scramble. The design is printed into the fibre, not laid on top: it won't crack or peel.

Machine wash at 30°C max, inside out, no fabric softener, and air dry (the full care guide).

In no-gi, IBJJF requires a black, white, or black-and-white base, with at least 10% in the belt colour. Check the dominant colour of the design against your tournament rules. At the club, on open mat, and in tournaments with no colour code, they work everywhere.
