Overview

Built for women who want minimal weight but maximum comfort in their adventures, the Women's Spark lineup demonstrates Sea to Summit's 100% commitment to building a sleeping bag that's made perfect for you.

Women's specific shape and body mapping result in warmth and comfort without the weight.

RDS-certified 850+ fillpower goose down treated with a non-PFC Ultra-Dry Down treatment provides superior insulation, while a technical hood and zipper draft tube prevent precious warmth from escaping.

A super-breathable 10D liner fabric rounds off the comfort profile, and a 10D shell with a non-PFC DWR combined with a highly water repellent hood and footbox fabric, keeps moisture out. Half zip.
