Updated Design For 2026 !

Evolution of the record-breaking PR Speed Suit. Premio-based short portion for exceptional comfort and improved aerodynamics, especially in crosswind conditions. CFD and in-depth wind tunnel testing create the fastest triathlon racing suit, optimized for high speeds.

When starting from a suit that already holds numerous (bike) course records and has achieved numerous 70.3 and long-distance victories in the past few years, potential for improvements might not be identifiable at first glance. But at Castelli we never tire of looking for that extra speed to provide a real performance advantage for top athletes. From extensive tests in the wind tunnel, we discovered significant differences in the leg portion, especially at certain yaw. That process led us to our fastest long-course race suit, which even provides improved comfort compared to its predecessor due to an almost seamless construction of the short portion and without any additional silicone gripper needed.
