Castelli Aria Shell 2 – ultralight men's cycling wind jacket

Castelli Aria Shell 2 Jacket – ultralight men's cycling wind jacket

The Castelli Aria Shell 2 Jacket is an exceptionally light and packable men's cycling wind jacket designed for cool starts, fast descents and rapidly changing conditions. Its close-fitting construction and breathable stretch panels provide a comfortable performance fit without excess fabric flapping in the wind.

Ultralight woven microfiber fabric on the front and back offers effective protection from cold airflow. Striped mesh panels at the sides and on the back of the sleeves add stretch, improve breathability and allow unrestricted movement in the riding position. The Aria Shell 2 protects the areas most exposed to wind while its breathable panels help release excess heat. This makes it particularly suitable for faster road rides in cool conditions when wind protection is needed without the insulation and bulk of a thermal cycling jacket. The jacket packs into its integrated stuff sack and takes up minimal space in a jersey pocket or saddle bag. A two-way YKK® Vislon® zipper makes it easy to regulate ventilation and provides convenient access to the rear pockets of your cycling jersey.
