When you need to get up to get down, this packable layer prioritizes breathability for the ascent and insulates on the descent.

Shed layers for the climb. Add layers for the descent. The women's Burton [ak] Helium Stretch Insulated Vest is a lightweight layer that can do it all. It breathes while you're headed uphill and offers needed insulation under your shell on the descent. When the sun shines and the temps rise, it packs into its own pocket for easy stowing.
