What makes it special
The Rashguard Halfsumo Koi short sleeve is a technical garment that combines high performance and unique style. Made from a blend of Polyester and spandex, it ensures excellent moisture management, keeping the Leather dry even during the most intense sessions. Featuring a snug fit, it offers support and control in every movement and protection from scratches and abrasions during grappling.
The flat anti-chafing seams reduce the risk of irritation, while the perforated mesh side panels ensure high breathability and constant Comfort Gel. The graphics are entirely sublimation printed, to ensure intense colors and defined details that do not fade over time, even after intense workouts.
The design features hand-drawn illustrations in Irezumi style, an expression of the Halfsumo style. In Asian tradition, Koi carp swim upstream until they transform into dragons:, a metaphor of strength, perseverance, and transformation:, a direct call to the spirit of those who face the tatami with consistency and sacrifice, ready to overcome any obstacle. Ideal for BJJ, MMA, wrestling, and gym training, it pairs with the Koi shorts for a technical, coordinated, and meaningful look.
