  • Crafted in a unique black 450gsm Pearl Weave kimono fabric, this backpack is a modern tribute to the classic BJJ Gis.

    Reinforced with durable 600D Nylon Cordura at key stress points, it’s built to handle rain, wet gym floors, and everyday wear. A dual-buckle system with an internal drawstring keeps your gear secure on the move.

    The water-resistant nylon lining lets you store sweaty training gear without moisture leaking through, and features custom irezumi-style artwork inspired by samurai and bushido lore.

    Removable Velcro patches add personality, with subtle BJJ references and the option to customize your look.

    Zippered side pockets and hidden compartments keep essentials like bottles, electronics, and valuables organized and separate.

    Fully washable for easy care—ready for every session.

OUR DESIGN PROCESS

The Half Sumo design process begins with the simplest tool: a line on paper.

Before a dogi, rashguard, grappling short, T-shirt, hoodie, or accessory becomes part of a finished collection, it starts as hand-drawn artwork. For co-founder and designer Luigi Scarcella Perino, drawing has always been a natural form of expression. Half Sumo Collective grew from that instinct, shaped by childhood afternoons spent reading manga, years of martial arts training, and a visual world built from Japanese woodblock prints, ukiyo-e, irezumi-inspired tattoo art, graffiti, street art, and combat sports culture.
