HUUB SUB7 Men's Trisuit

Born from the SUB-7 Project, this swimskin is engineered for one purpose: absolute speed in non-wetsuit swims. Hydrodynamic efficiency prioritised above all else, nothing added, nothing wasted. The SUB-7 Project marked a defining moment in triathlon—pushing athletes, engineers, and technologists to rethink what was possible at the limits of performance. It didn’t just change race-day expectations. It changed how we think.

That shift directly shaped our most advanced developments. The SUB-7 Swimskin is the result. Built through relentless testing and analysis of hydrodynamic drag, surface interaction, body position, and speed optimisation, it was designed with one uncompromising objective: maximum speed in non-wetsuit swims. Along the way, one truth became clear: comfort, durability, and versatility often come at the cost of outright performance. For SUB-7, speed came first.

• Developed within the SUB-7 performance programme for non-wetsuit racing
• Hydrodynamically optimised fabrics selected for minimal surface resistance
• Precision seam and panel control to reduce drag and water disruption
• Compression mapping to support body position without restricting stroke mechanics
• Race-legal construction focused purely on in-water speed
• Minimalist design philosophy prioritising performance over comfort features
