When summer heats up, Troy Lee Designs' Men's Ace Jersey keeps you cool via a full-length zipper and lightweight, moisture-wicking polyester fabric. As you sweat, the soft knit pulls moisture away from your skin to keep you dry and comfortable, so you can focus on crushing the climb, not on fighting off the sweat that's dripping down your back and pooling in your chamois. Troy Lee also gives the Ace three rear pockets and a fourth zippered pocket so you're able to stash water, snacks, and a mulitool without having to lug a pack around. Inside, a half-circle media port makes it easy to run headphones up to your noggin without getting tangled up in cables, and reflective trim helps drivers spot you when you're pedaling along the road on your way back to the trailhead.
