Big Agnes designed the Women's Ethel Sleeping Bag for campers and backpackers who aren't willing to compromise comfort or performance. Its DownTek water repellent treatment helps the light and lofty down insulation retain its warmth in wet weather. Insotect Flow construction offers a revolutionary baffle design that mixes vertical chambers with Flow Gates to minimize shifting and deliver uniform heat distribution for near subzero temperatures. A contoured design places the Ethel Sleeping Bag somewhere between a packable mummy and a roomy rectangular. Big Agnes treated the ripstop shell for water resistance and the soft lining with stain resistance for extra protection. There are also draft protectors at the collar, wedge, and down the full length zipper. An integrated pad sleeve requires you to pair the Ethel with an accommodating sleeping pad for insulation at the bag's bottom.
