Castelli Aria Vest Dames, bruin

Near weightless protection
Castelli has reinterpreted the classic wind vest to make it as svelte as the rest of your wardrobe. This vest is designed to completely block the wind on the front while allowing ample breathability on the back. The fabrics are so impossibly light that you'll be surprised at how much warmer you stay with this vest over your standard jersey. But the magic comes from the cut and the stretch fabric on the back, which take up all the loose fabric and make the vest fit close to body without feeling tight or looking ridiculous. When you're ready to take it off, the vest folds into its rear pocket and stashes away, taking up minimal space in your jersey pocket.
