NO MORE OLD WIND JACKET

The Aria Shell Jacket is a very different beast from your old baggy jacket that either didn't protect you or didn't breathe. This jacket is an incredibly lightweight layer that blocks the wind on the front of your body and also provides great breathability thanks to the mesh side panels. But what you'll really appreciate is the stretch panels on the sides and back of the sleeves that make this jacket fit like a second skin. No loose fabric, no cold air circulating inside the jacket, no more looking like an Armstrong-era cyclist.

This jacket is light and warm enough to wear throughout a workout in mild temperatures. When you take it off, it packs into a pocket on its side panel and stores in a minimum of space in your pocket or saddle bag.

WHAT IT IS
