CASTELLI Free Sleeveless Tri Jersey for Women: Unrivaled Triathlon PerformanceDominate every leg of your race with the CASTELLI Free Sleeveless Tri Jersey, the ultimate triathlon companion engineered specifically for the female athlete. Designed for those who refuse to compromise on speed, comfort, or performance, this jersey is a masterclass in multisport apparel. From the moment the starting gun fires to your final stride across the finish line, every detail of this top is meticulously crafted to give you a competitive edge. This women´s specific, sleeveless tri jersey is your key to seamless transitions and race-day comfort.Glide through the water with unparalleled efficiency. The jersey features a revolutionary hydrophobic treatment that actively repels water instead of absorbing it. This means you emerge from the swim with a top that is virtually dry, incredibly light, and won´t weigh you down during the critical transition to the bike (T1). The fabric's surface allows you to move through the water with less resistance, helping you conserve energy and exit the swim feeling fresher and faster.Once on the bike, the Free Sleeveless Tri Jersey truly reveals its aerodynamic prowess. The back is constructed from a wind-tunnel-proven Velocity mesh fabric, a design choice that is all about slicing through the wind and saving precious watts. This advanced material and its anatomical, body-hugging fit reduce drag, allowing you to maintain higher speeds with less effort. The exceptional stretch of the fabric ensures a full range of motion in the aero position without any restriction, while the sleeveless cut provides complete shoulder freedom.Comfort is paramount, especially as you head into the final leg. The run is where gear can make or break your performance, and Castelli has left nothing to chance. The innovative, chafe-free underarm construction eliminates a common source of irritation, allowing you to maintain your natural arm swing without rubbing or discomfort. The soft, round neck and the clever without zipper design further enhance comfort, removing any potential pressure points on the run and ensuring a smooth, irritation-free fit under a wetsuit. To keep the jersey perfectly in place, Castelli employs their signature GIRO3 elastic at the arms and back, providing a secure grip that doesn´t dig in or constrict. This combination of features ensures you can focus solely on your performance, not on your apparel.Features:* Hydrophobic treatment is fast in the swim and doesn't absorb water* Velocity mesh back gives wind tunnel proven speed on the bike* GIRO3 arm and back elastic* Chafe-free underarm constructionSpecifications:* Weight: 67 g
