KOJO Fightwear is a US-based jiu-jitsu apparel brand and an offshoot of BJJ Fanatics. Based in Beverly, Massachusetts, it makes training gear for practitioners who treat jiu-jitsu as part of their lifestyle, with a range that covers gis, rashguards, shorts, and training accessories.

The collection combines everyday training essentials with designs built around places, teams, collaborations, and grappling culture. Alongside ready-to-wear gis and rashguards, KOJO offers T-shirts, sweatshirts, accessories, and custom gear for academies, including adult and youth options.

The name KOJO refers to constant improvement: showing up, learning from mistakes, and getting a little better over time. That idea gives the brand a broad position in the BJJ market, with gear for gi and no-gi training as well as casual pieces that carry the same connection to Brazilian Jiu-Jitsu.
