In it to win it.

Castelli understands the demands of racing triathlon, which is why they've worked hard to give you tri clothing you can rely on when you're rushing through lightning fast transitions or powering through grueling hills on the bike course. Throw on the Men's Free Tri Sleeveless Top when you peel off your wetsuit and make a beeline for your bike. SpeedFreak ventilated fabric on the front panel and Velocity mesh in the back work together to ensure optimal breathability and quick-drying properties after you hop out of the water and the slim fit keeps you aerodynamic while you're speeding through the course. Two back pockets stash a few emergency energy gels in case you start to bonk at mile 30. When you swap bike shoes for runners, use the SnapLock fasteners to clip your jersey to your shorts so it doesn't ride up, and enjoy a chafe-free sprint to the finish line thanks to the soft-finish armholes.

Not for the pudgy, medium, or slender

    WTF? I bought an XL and I actually needed help getting out of it. I am sure it's superb for the work but it felt like wearing a small condom. And maybe picture without the sleeves eh?
