Aria Shell Wind Jacket

Castelli Aria Shell Wind Jacket Castelli's Aria Shell reinvents the wind jacket. No more flapping fabric and no chance of overheating this jacket is incredibly light, close-fitting yet unrestrictive, windproof, and resistant to light rain. Breathability is retained thanks to mesh side panels, and it fits like a second-skin with stretch in the sides and the backs of the sleeves. There's a rear pocket for small items, and when you want to take it off, you can fold the jacket into its own pocket for compact storage.
