RIEL 05 MEN'S TRISUIT - Grey

The Riel 05 trisuit represents the pinnacle of Santini engineering for triathlon, developed in collaboration with elite athlete Marten Van Riel. Designed for long-distance racing, it delivers professional-level performance thanks to an aerodynamic fit with extended sleeves and legs, engineered to maximize efficiency during the cycling leg. All fabrics have been aerodynamically tested to ensure optimal drag reduction and consistent performance in race conditions.

The upper features front panels with advanced moisture management, capable of dissipating sweat up to twice as fast as the Viper model, promoting more effective evaporative cooling during the run. The construction is based on advanced material mapping, with aerodynamic fabrics on the arms and upper back and highly breathable zones on the chest and underarms, optimized through digital twin analysis for all three triathlon disciplines: swim, bike, and run. The lower section is made from raw-cut compressive fabric to support muscle recovery and includes an internal leg grip, while the external anti-slip insert in the groin area ensures stability in the saddle. The IMG chamois with Tower Gel Core technology provides comfort and shock absorption over long distances.

Testing between 40 and 50 km/h shows a performance advantage* of +2.5% compared to the Viper model, equivalent to approximately 7 watts saved and up to one minute gained over 80 km. This trisuit is ideal for triathletes seeking maximum aerodynamic efficiency and comfort in endurance races.
