Castelli Aria Shell Jacket Silver Grey

Not Your Old-Style Wind Jacket

In reality, the Castelli Aria Shell Jacket is very different from your flappy old jacket that either didn't protect you or didn't breathe. This jacket is an impossibly light layer that keeps the wind off the front of your body while allowing ample breathability through the mesh side panels.

But what you'll really appreciate is how Castelli have designed the stretch panels in the sides and on the back of the sleeves to make this jacket fit like a second skin: no flapping fabric, no cold air circulating inside the jacket, no more looking like a throwback to the Armstrong era.
