You've trained hard, from pool to track and spin class, and you're ready for your first triathlon, but don't forget your Castelli Core 2 Top for Men. This ultra-breathable sleeveless top is ready for every discipline, featuring Castelli's Tempo 3 Light fabric that wicks away sweat just as it beads, and pulls away moisture before you can feel it drip, to keep you as cool as possible from the starting line to podium. The Core 2 Top is built to feel lightweight against your skin, with a convenient 1/4-zip for quick venting when the mercury rises. It fits snug without being constrictive, so you can ride and race in comfort when the pressure is on and you're pushing to the front of your heat.
