Featuring a body-mapped mix of synthetic and hydrophobic down insulations, the Marmot Women’s Astrium 30 Degree sleeping bag expertly balances thermal efficiency, weight and comfort for cool-to-mild weather backpacking and camping.
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.
Extensive scientific research and testing to optimize body mapping of different insulation types resulted in Marmot’s creation of the Women’s Astrium 30 Degree sleeping bag, which is a member of Marmot’s family of Composite Bags. This unique construction combines certified 650 fill power down treated with Marmot’s Down Defender water repellent treatment that allows the down to stay drier 10 times longer than untreated down in damp conditions with Marmot’s Spirafil synthetic fill to optimize warmth while reducing weight and bulk. The down layer is situated within the top side of the bag to provide extra warmth to the core of the body while the synthetic insulation fills the back side of the bag to provide maximum warmth in compression zones between the body and the ground or sleeping pad. Over all, body-mapped insulation allows the Women’s Astrium 30 Degree bag to offer superior thermal efficiency without bulkiness or added weight.
Other features found in the Women’s Astrium 30 Degree include a contoured, ergonomic hood that helps reduce heat loss and keeps your head warm and comfortable. A snagless draft tube sewn behind the full length zipper keeps cold air from reaching the inside of the sleeping bag and zippers from getting caught and creating damaging tears in the fabric. A Velcro-free face muff, two hang loops and zipper guards are also integrated.
The Marmot Women’s Astrium 30 Degree sleeping bag fits up to 5’ 6". A stuff sack and storage sack are included.
