Sea to Summit Altitude ATI (-4C, down, women's)

Yay! A lightweight, compact bag great for backpacking yet in a roomy tapered rectangular shape. No more mummy-bag claustraphobia. The Altitude is made of high quality down and super light fabrics with a full round-the-foot zip plus another half zip on the other side. The bag is designed to zip with another. Vertical baffles over the chest ensure the down cannot migrate to the outside of the bag while you're sleeping. There is an internal zip pocket for essentials and the bag comes with Ultra-Sil compression bag and storage cell.
