Women's 2026 Castelli Free Sanremo 3

The Women's Castelli Free Sanremo 3 Sleeveless Tri Suit (2026 model) is Castelli's premier high-end one-piece triathlon suit, refined over years as an evolution of the legendary Sanremo platform—optimized for long-distance racing in hot, demanding conditions like Ironman events.

This sleeveless design emphasizes superior ventilation and heat management with lightweight, highly breathable fabrics on the main body (including Velocity mesh panels for maximum airflow). CFD-optimized fabric placement and seam construction reduce aerodynamic drag for measurable speed gains on the bike. The standout feature is the integrated internal neck pocket for loading ice cubes to lower core temperature during scorching races (perfect for Kona or summer 70.3s). It includes a full-length front zipper for easy ventilation and fast transitions, the proven KISS Tri seat pad for long-ride comfort, Forza2 Stretch leg fabric with debossed structure for better airflow and fit, soft fabric overlap around the neck to prevent chafing, and a women-specific race-fit cut that delivers unrestricted movement across swim, bike, and run.

Built for serious triathletes prioritizing speed, comfort, and thermal regulation, it remains a top choice for elite performance in warm-weather racing.
