Castelli Free Sanremo 3 Women's Sleeveless Triathlon Suit Small - Long Distance Aero Race Trisuit | Cycling Gears Hub

Take on your longest distance races with the Castelli Free Sanremo 3 Women's Sleeveless Tri Suit, a true evolution of Castelli's iconic, best-selling triathlon suit. Designed for performance-driven triathletes, this suit trades the on-bike aerodynamic advantage of sleeves for the added freedom of movement and cooling benefit of a sleeveless design, while retaining every ounce of full race performance found throughout the Free Sanremo lineup.

CFD-Based Aerodynamic Design:
The Castelli Free Sanremo 3 is engineered using CFD-based fabric placement and advanced seam construction, reducing drag at race speeds while ensuring a comfortable, secure fit across all three triathlon disciplines. This scientific approach to fabric layout and seam positioning reflects Castelli's continued investment in wind tunnel testing and computational fluid dynamics to deliver measurable performance gains on race day.

Sanremo Front Opening:
A signature feature of this suit is the Castelli Sanremo front opening, which allows for easy flexibility when transitioning between cycling, running, and swimming positions. This overlapping front design also enables quick cooling and convenient nature breaks during long-distance races, while avoiding uncomfortable folds when hunched over in the aero bike position, and preventing bunching when fully stretched out during the swim and run legs.

Cooling and Temperature Regulation:
This suit includes an internal ice pocket positioned in the neck area, allowing athletes to insert ice cubes to help regulate body temperature during hot race conditions, a valuable feature for long-distance events held in extreme heat. The main body uses lightweight, breathable fabric that optimizes cooling and comfort throughout the entire race, helping to manage sweat and maintain a comfortable core temperature from start to finish.

Comfort-Focused Details:
Soft fabric overlays around the armholes prevent chafing and irritation, ensuring comfort during the run leg when arm movement is at its most repetitive. Two rear pockets lie flat against the body and are designed to prevent bouncing, allowing athletes to securely store nutrition or race essentials without discomfort or distraction during high-intensity efforts.

Forza2 Stretch Leg Fabric and KISS Tri Seat Pad:
The lower portion of the suit is constructed using Castelli's aero-optimized Forza2 Stretch fabric, delivering both aerodynamic advantage and maximum comfort throughout the ride and run. Silicone leg grippers keep the leg endings securely in place without pinching or riding up, eliminating unwanted movement during transitions or high-speed efforts. The suit also features Castelli's KISS Tri seat pad, offering excellent comfort and support on the bike while remaining virtually unnoticeable during the run, striking the ideal balance between cycling comfort and running performance.

Sun Protection:
This suit offers UPF sun protection, adding an extra layer of defense against harmful UV rays during long hours of outdoor racing, an important consideration for triathletes competing in extended distance events under direct sunlight.

Ideal Use Cases:
The Castelli Free Sanremo 3 Sleeveless Tri Suit is ideal for female triathletes competing in 70.3 and full-distance triathlon events, where comfort, cooling, and freedom of movement matter as much as aerodynamics. It is particularly well suited for athletes racing in hot climates who prioritize ventilation and temperature regulation, or those who prefer the added range of motion a sleeveless suit provides during the run leg.
