Sierra Designs Womens Nitro 800 20 Degree Down Sleeping Bag

Simple construction and a classic mummy bag shape are the hallmarks of one of our best-selling sleeping bags for backpackers who put a premium on low weight, incredible comfort and straightforward tech.

The Sierra Designs Women's Nitro 20 sleeping bag is designed with durable nylon ripstop and insulated with 800-fill, hydrophobic DriDown™ to keep you toasty warm, even on damp nights.
