A versatile option for 3-season backpacking or camping, the Marmot Women's Radium 20 Degree sleeping bag utilizes high-performance down insulation that has been treated to offer bolstered weather resistance.
Marmot accounts for the anatomical differences between male and female campers and hikers when constructing gender-specific sleeping bags. Increased insulation in key areas better addresses those areas where women most often experience heat loss. A tapered cut provides a narrower fit at the shoulders and a wider flare at the hips to ensure a comfortable fit and maximum thermal efficiency. The shorter lengths of Marmot's women's bags help to avoid cold spots and make certain that your body isn't working unnecessarily to heat uninhabited areas of the bag.
Fill power measures the loft, or "fluffiness," of down insulation and Marmot goes to great lengths to guarantee the 650+ certification found in the Radium bag. Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel and, despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet, but Marmot combats this by applying a Down Defender water repellent treatment that allows the down to stay dry longer, maintain loft, and dry faster than untreated down. Most importantly, it retains its ability to keep you warm even if damp or wet. Polyester and nylon ripstop exterior fabrics with a DWR treatment further protect the insulation.
Eliminating cold spots and providing comfort, sewn-through baffles ensure that insulation is evenly distributed throughout the bag. Ground-level side seams make it difficult for body heat to escape through the zipper and a draft tube seals cold air out of the bag along the zipper. An ergonomic hood helps to reduce heat loss and an insulated draft tube behind the full-length zipper keeps cold air from keeping in from the side of the bag. Zipper guards help to avoid irritating and damaging snags and two-way sliding zippers allow venting on warmer nights. An anatomically-shaped footbox is wider at the toes and narrower at the heels, providing a more natural fit while enhancing warmth and comfort.
The Marmot Women's Radium 20 Degree sleeping bag is available in Regular (fits up to 5' 6") and Long (5' 10") lengths. A stuff sack and a storage sack are included.

Real Customer Reviews
- Warm, lofty down bag.
Likes: The packed weight and dimensions tell you everything you need to know about how small this bag is, the question I always have is how well the down does once compression is released. The answer on this bag, is excellent. Great loft and distribution of the down, which is the main factor in a warm bag that keeps you comfortable all night.
Dislikes: My wife is five feet tall. The smallest size on this bag is a little long for her.
