The Castelli Free Sanremo 3 Sleeveless Women's Cycling Suit in White Black and Dark Night Shade Vivid Orange is a high-performance one-piece race suit designed specifically for female triathletes and endurance athletes who demand the perfect balance of aerodynamics, comfort, and efficiency. Developed using feedback from elite professional athletes and refined through years of racing innovation, this premium sleeveless suit is engineered to help you achieve your best performance in every stage of a triathlon, from the swim start to the finish-line sprint.

At the center of its design is Castelli's revolutionary Sanremo front-opening construction, a feature that has become one of the most recognized innovations in triathlon apparel. Unlike conventional one-piece race suits, the Sanremo system allows the front of the suit to open completely, providing exceptional ventilation during hot-weather racing while offering added convenience during long-distance events. This unique construction allows athletes to regulate body temperature more effectively and provides greater comfort without sacrificing the aerodynamic advantages of a one-piece suit.

Constructed from premium Italian technical fabrics, the Free Sanremo 3 delivers outstanding breathability, lightweight comfort, and muscle-supporting compression. The advanced stretch materials conform naturally to the female body, creating a streamlined second-skin fit that minimizes aerodynamic drag while maintaining unrestricted flexibility. Carefully engineered compression supports key muscle groups, helping reduce fatigue, improve circulation, and maintain consistent performance throughout long races and demanding training sessions.

The sleeveless design provides complete freedom of movement for the shoulders and upper body, making it ideal for efficient swimming while also increasing airflow during the cycling and running segments. Combined with the women's-specific ergonomic race cut, the suit follows the body's natural contours to provide exceptional comfort without restricting movement. Every panel has been strategically positioned to optimize flexibility, improve fit, and maintain an aerodynamic profile at race speeds.

Temperature management is another area where the Free Sanremo 3 excels. The moisture-wicking fabrics rapidly transport sweat away from the skin while allowing heat to escape efficiently, keeping athletes cool, dry, and comfortable even during intense efforts. The quick-drying construction also minimizes water retention after the swim, reducing unnecessary weight and ensuring a smoother transition into the bike leg.

For cycling comfort, the suit features Castelli's premium KISS Tri seat pad, specifically developed for multisport competition. The anatomically shaped chamois provides targeted cushioning and vibration absorption during the cycling segment while remaining thin and flexible enough to remain virtually unnoticed during swimming and running. Its low-profile design eliminates bulk while still delivering the support required for long hours in the saddle.

Flatlock seam construction further enhances comfort by minimizing skin irritation and preventing chafing during repetitive movement. Every seam is carefully positioned to maximize durability while maintaining a smooth feel against the skin throughout extended races.

Practical functionality is integrated into the design with rear nutrition pockets that securely hold energy gels, nutrition bars, or race essentials. Positioned for easy access without disrupting the aerodynamic silhouette, these pockets allow athletes to maintain their fueling strategy while staying focused on performance.

The shorts are equipped with silicone-backed leg grippers that provide a secure yet comfortable fit, preventing unwanted movement without restricting circulation. This ensures the suit maintains its streamlined shape throughout swimming, cycling, and running while enhancing overall comfort during prolonged use.

Premium UV-protective fabrics help shield the skin from prolonged sun exposure during outdoor competitions and long training sessions. Reinforced stitching, durable elastic components, and high-quality construction ensure the suit retains its compression, elasticity, and performance characteristics after repeated racing and washing.

Available in the sophisticated White Black colorway for a clean, professional appearance and the vibrant Dark Night Shade Vivid Orange design for athletes seeking a bold race-day look, the Free Sanremo 3 combines technical excellence with unmistakable Italian style.

Ideal for Sprint Triathlons, Olympic Distance, Half Ironman, Full Ironman, Road Cycling, Time Trials, Endurance Racing, Multisport Events, and Performance Training, this suit is built to meet the demands of serious athletes pursuing peak performance.

The Castelli Free Sanremo 3 Sleeveless Women's Cycling Suit represents the perfect fusion of innovation, comfort, and speed. From its advanced Italian fabrics and aerodynamic women's-specific fit to its patented Sanremo construction and race-proven KISS Tri seat pad, every detail has been engineered to help athletes swim more efficiently, ride faster, and run stronger. Whether you're preparing for your first triathlon or competing at the highest level, this premium race suit delivers the confidence, comfort, and performance trusted by elite athletes around the world.
