RND1. MMA Apparel was founded in Belfast by Cállum Carville, better known as Mr RND1. — a ClanWars Middleweight Champion, Freestyle Kickboxing Black Belt and experienced competitor across MMA, boxing, kickboxing and Brazilian Jiu-Jitsu.

With over 10 years of martial arts experience, Cállum recognised a gap in the market. Quality, personalised fightwear was often overpriced and inaccessible to everyday fighters. He set out to change that, establishing RND1. as one of the early brands pushing to make custom fightwear more affordable, accessible and personal.

Unlike brands built around combat sports purely as a business, RND1. was built by someone who has actually stepped into the cage, competed and experienced the sacrifices fighters make.

Through extensive research, experimentation and product development, RND1. has grown into a fightwear brand offering everything from rash guards and MMA shorts to bespoke fight kits, training apparel and club merchandise.

But RND1. is about far more than selling fightwear or handing out sponsored kits.

We believe supporting fighters means building genuine relationships, helping athletes develop their identity, promoting local talent, creating opportunities for exposure and working alongside gyms, clubs and competitors at every stage of their journey.

Whether you’re preparing for your first competition, representing your club or competing at championship level, our commitment remains the same: delivering quality products, affordable customisation and meaningful support from people who understand the sport.

We’re not just another fightwear brand looking for fighters to wear our logo. We’re a fighter-founded brand invested in the people behind it.
