CASTELLI Sanremo S Short Sleeve Race Suit: The Evolution of SpeedExperience the pinnacle of aerodynamic engineering and race-day comfort with the CASTELLI Sanremo S Short Sleeve Race Suit. This isn´t just another piece of cycling clothing, it´s the next evolution of the suit that started a revolution, meticulously designed for cyclists who demand every possible advantage. Whether you´re attacking in a road race, pushing your limits in a time trial, grinding gravel, or powering through an MTB course, the Sanremo S is your ultimate weapon against the clock and the competition.Born from a relentless pursuit of aerodynamic perfection, this men´s race suit embodies the fusion of science and performance. Its design begins with extensive Computational Fluid Dynamics (CFD) analysis, leading to a revolutionary CFD-based fabric placement and seam construction that intelligently manages airflow across the body. The shoulders, a critical area for drag, feature a specially engineered fabric proven to reduce drag at race speeds, providing as much as a 6% savings in CdA. This is enhanced by a secondary aero-optimized fabric that delivers a further 3% decrease in CdA, giving you a tangible, measurable advantage when seconds count.While built for pure velocity, the Sanremo S never compromises on comfort. The lightweight body fabric offers exceptional cooling and breathability, keeping your core temperature regulated during the most intense efforts. For an impeccable fit that moves with you, the suit incorporates the aero-optimized Forza2 Stretch fabric, which provides outstanding comfort and muscle support without restricting movement. The comfort details are refined to perfection, from the bonded sleeve endings that lie flat against the skin to the silicone leg grippers that ensure the leg endings stay precisely in place, lap after lap.At the heart of the suit´s all-day comfort is the legendary Progetto X2 Air Seamless seat pad. Renowned for its variable thickness, seamless construction, and skin-care layer, this chamois provides pro-level cushioning and support, ensuring you remain comfortable and focused, even on your longest and most demanding rides. The Sanremo S represents the perfect synthesis of a skinsuit´s aero benefits and the convenience of a separate jersey and shorts, a design Castelli pioneered. Weighing in at a mere 305g, this suit is a masterclass in lightweight, uncompromising performance.Technical Specifications:* Aerodynamics: CFD-based fabric placement and seam construction.* Shoulder Fabric: Engineered for drag reduction, offering up to 6% savings in CdA.* Aero Fabric: Delivers a 3% decrease in CdA for maximum speed.* Body Fabric: Lightweight for optimal cooling, breathability, and comfort.* Lower Body Fabric: Aero-optimized Forza2 Stretch for a perfect fit and aerodynamic advantage.* Sleeves: Short sleeve design with bonded endings for superior comfort.* Leg Grippers: Silicone grippers to keep leg endings securely in place.* Seat Pad: Progetto X2 Air Seamless for long-distance comfort.* Weight: 305gIdeal Use:* Road Cycling* Time trial* Gravel cycling* MTB Cycling
