ATHLETIC CLUB: OLD SCHOOL DISCIPLINE. MODERN PERFORMANCE.

The Athletic Club short sleeve BJJ rashguard is for the athlete who shows up, puts in the work, and lets the training speak. Black. Clean. Built to handle whatever the round throws at it.

Where most rashguards fail you is the details — seams that dig in by round three, a waist that rides up mid-scramble, graphics that crack and peel after a season of washing. The Athletic Club is built around eliminating those distractions. Flatlock seams stay flat against the skin no matter how physical things get. The silicone waist grip keeps everything locked in so you’re not adjusting your gear between exchanges. Compression fit that actually moves with your body, not against it — so when you’re defending a takedown or pushing the pace on the feet, your rashguard is the last thing on your mind.

The old school gym didn’t care about logos. It cared about who put in the work. That’s the gear you’re wearing.

Common questions

Is this IBJJF approved?
No. This is not intended as a ranked IBJJF rashguard. It is built for training rather than to meet competition ranking requirements. If you compete, check the current IBJJF rulebook for what your division allows.
Will the graphics fade or peel?
No. The graphics are fully sublimated, which means the ink is bonded into the fabric rather than printed on top. There is nothing to crack or peel.
How should I wash it?
Cold wash, hang dry. Avoid fabric softener and the tumble dryer — both shorten the life of compression fabric.
Is it tight or loose?
Athletic compression fit. Snug against the body without restricting movement. Between sizes? Size up for a slightly looser feel.
What if I order the wrong size?
Your first size exchange is free. Unused, unwashed, in original packaging, within 14 days of delivery.
How long does shipping take?
Every item listed as available is physically in our inventory — no production delays. Orders ship from Québec within 1–3 business days.
