Castelli Stealth T1 Top

The wind tunnel testing on the Castelli Stealth T1 Top showed a 3-minute advantage on a 5-hour Iron Man bike leg. In the triathlon world, three minutes could mean a jump or a drop in rankings. Castelli has specialized in making triathlon apparel to help the end results of possibly one of the most demanding endurance sports. The Stealth T1 top is used to slip on over one of the Castelli tri suits to create an even smoother, slicker surface for wind to flow over effortlessly. Velocity fabric on the front serves several essential objectives of a high quality cycling top. The fabric has enough of a stretch to maintain full contact with the skin. Besides having excellent aerodynamic qualities, there is also another purpose for the fabric used in the Castelli cycling top. Within the design, air can circulate to keep skin cool and fresh as the body heats up. Very lightweight and airy, you will not overheat in this top. In essence it even goes further to help cool you down. The aerodynamic qualities of the Velocity Mesh on the back and the shoulder are combined with a wicking and evaporating capacity which keeps you dry. Keeping dry is one more critical quality when your body needs to stay in its ideal performance temperature. The Camlock zipper on the front is easy to open up to let in some cool air as you ride in the aero bars, trying to beat the clock in perhaps very warm weather. The elastic waist keeps the cycling jersey from creeping up as you are in the aero position, but the silicone gripper elastic does not pinch the skin.
