Castelli Aria Vest

Castelli has reinterpreted the classic wind vest to make it as slim as the rest of your wardrobe. This vest is designed to completely block the wind on the front while on the back it allows ample breathability. The fabrics are so incredibly light that you will be surprised how warmer you feel when you wear this vest over your shirt.

But the magic comes from the cut and stretch fabric used on the back, which makes the vest fit close to the body without being too tight or avoiding making you look ridiculous. When it's time to take it off, the vest disappears completely into the back pocket of your jersey, taking up as little space as possible.

• Very light windproof microfiber front fabric

• The striped mesh back is stretchy to prevent the fabric from fluttering in the wind

• It folds up into an extremely small space

• Back pocket
