Buying guide
Best-seller rash guards: how to choose among our best sellers
The buying guide in 6 photos. Tap a photo, the answer opens below.
01Why start with a best-seller?
Because a rash guard is judged over time. The one you keep doesn't ride up during a guard pass, doesn't rub under the arms, and keeps its design wash after wash. The pieces on this page are the ones our customers choose the most: a solid starting point for a first rash guard, or a safe pick to round out your bag.
In the photo: Hexagon Short-Sleeve - Men02Plain, Japanese or illustrated: which best-seller for which use?
A plain black design, like Minimal Red Line, goes everywhere: club, open mat and no-gi tournaments, where the IBJJF requires a black, white, or black-and-white base. Japanese-inspired designs, Ronin in the Rain, Raijin or Red Armor Samurai, suit those who want to wear a story. Claws and camo designs make a rawer statement, for the club and MMA. Flag designs, like French Pride or Hexagon, are worn to represent your country in competition or at a training camp.

03Which cut for which practice?
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.
04How do I measure myself?
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.

05What fabric, what care?
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 the photo: Ronin in the Rain Short-Sleeve - Men06Best-seller rash guard at competition
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.
