Bells X JR Rashguard

Introducing the Bells x JR Performance Rashguard — a special collaboration with Renato Junior, our head of BJJ and Grappling coach. Designed for demanding athletes, this rashguard combines premium comfort and durability with Renato’s vision for functional performance on the mats. Made with high-quality 270 gsm fabric, it offers a snug fit and lasting protection. The silicone strip at the hem keeps it perfectly in place during rolls and scrambles. Tested and approved by JR himself — train harder, roll smarter.
