Castelli Aria Shell 2 Jacket - Women's Silver Gray, L

What Our Gearhead(R) Experts Are Saying:"I keep the Aria Shell 2 Jacket in my pocket for cool starts and windy descents. It's super light, fits like a second skin, and vents well thanks to the stretchy mesh at the sides and sleeves. Plus, it packs down tiny-barely takes up any room when I don't need it."We slip the Aria Shell 2 Jacket into our back pocket before heading out into shoulder-season temps and unpredictable conditions. Lightweight, stretchy, and wind-blocking where it counts, this packable shell gives us just enough protection without weighing us down or trapping heat when the ride intensity ramps up. The windproof microfiber front and sleeves block chilly gusts, while breathable mesh panels at the sides and sleeve backs let excess heat escape. It packs into its own integrated stuff sack, making it easy to carry and quick to deploy when the clouds roll in or the descent gets long. Clean lines, a two-way zipper, and reflective logos make this a polished and functional go-to layer for transitional rides.
