Improved breathability:
A draft flap along the zipper allows you to unzip for maximum airflow while keeping the jacket in place instead of flapping in the wind.

Packable convenience:
This jacket stuffs into a built-in mesh backpack, so it's easy to take off, stow, and keep running when the weather warms up.

Wind & water protection
Breathable DriLayer® Seal fabric lets excess heat out without letting the elements in.
