Aria Bike Jacket

Castelli reinvents the classic ultralight wind jacket in the amazing Aria. In reality, it's very different from your flappy old wind jacket that either didn't breathe or didn't protect you. This one is an impossibly light layer that keeps the wind off the front while allowing extreme breathability through mesh side panels. But what's really unique is how they use the stretch panels in the sides and on the back of sleeves to make the Aria fit like a second skin. No flapping, no cold air circulating inside, folds into its own side panel pocket and stuffs away in your jersey pocket or seat bag. Best used in temperatures of 50-65 degrees and meant to be worn very fitted.

• ultralight, windproof, woven microfiber front
