Sanremo S Tri Speed Suit - Men's

What Our Gearhead® Experts Are Saying:

"This is the go-to for serious racers. Its aerodynamic design saves energy on race day, and the Progetto X2 chamois keeps me feeling fresh even after hours in the saddle. Plus, it stays put thanks to the silicone leg grippers."

When it comes to race-day performance, the Sanremo S Speed Suit redefines fast. With CFD-based fabric placement and bonded seam construction, this suit is optimized for minimal drag, reducing aerodynamic resistance by as much as 6% in Castelli’s C4A wind tunnel testing. The Forza 2 Stretch fabric provides breathability, support, and aerodynamic efficiency, ensuring we stay cool and comfortable during high-intensity efforts.

The minimalist design doesn’t compromise on comfort. Bonded sleeve endings reduce irritation and create a seamless transition to our skin, while the lightweight bib straps provide a secure fit without adding unnecessary bulk. The Progetto X2 Air Seamless chamois delivers exceptional support, making even the longest rides manageable. Silicone leg grippers keep everything in place, ensuring the perfect fit through sprints, climbs, and descents.

Built for those who demand the best, the Sanremo S Speed Suit is our ultimate choice for achieving new personal bests on the bike.
