Marmot Helium 15 Degree Women's (2008) Sleeping Bag

Product Highlights

Updated for 2008! Weighing slightly less than 2 lbs., the high-performance Marmot Helium 15 Degree Women's sleeping bag offers 3-season versatility for female backpackers. An array of features and 850+ fill down provide lightweight, compressible functionality for backcountry adventure.

Marmot accounts for the anatomical differences between male and female campers and hikers when constructing gender-specific sleeping bags. Increased insulation across the chest and in the foot box of down sleeping bags 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.

The Helium 15 Degree Women's bag is insulated with certified 850+ fill goose down. Fill power measures the loft or "fluffiness" of down insulation and Marmot goes to great lengths to guarantee the 850+ certification with a battery of in-house and external verifications. 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.

Despite its lightweight construction, the Helium 15 Degree Women's sleeping bag makes no sacrifice with regards to performance and features. Eliminating cold spots and providing comfort, sewn through baffles ensure that the insulation of the Helium 15 Degree Women's bag is distributed evenly. Ground-level side seams create a barrier against cold air. A contoured, ergonomic hood mirrors the design of Marmot's popular outerwear jackets, helps reduce heat loss and keeps your head warm and comfortable. An integrated hood muff and passive collar snugly protect your face and head by keeping cold air from sneaking into the Helium 15 Degree Women's bag. An insulated oversized draft tube sewn behind the full-length zipper keeps cold air from reaching the inside of the sleeping bag and zipper guards help to avoid irritating and damaging snags. Marmot's patented Trapezoid Foot Box is wider at the toes and narrower at the heels, providing a more natural fit and improving warmth and comfort.

The Marmot Helium 15 Degree Women's sleeping bag fits to 5'6" and includes a stuff sack and storage sack.
