Mountain Hardwear Switch 35 Degree Women's (2009) Sleeping Bag

Product Highlights

Updated for 2009! The Mountain Hardwear Switch 35 Degree Women's sleeping bag is a unique offering that includes a built-in expander. The 35 Degree temperature rating and mummy-cut ensure that women stay warm on mild or warm-weather backpacking and camping trips. An integrated zipper allows the girth of the bag to increase by 8 inches for balmier nights or instances when you'd prefer to stretch out.

Recognizing that there are differences in the average dimensions and sleeping preferences of men and women, Mountain Hardwear offers a line of sleeping bags built especially for women. Increased insulation in the torso and in the footbox better addresses those areas where women most often experience heat loss. Designed with anatomically tapered cuts and shorter overall lengths, Mountain Hardwear's women's bags better accommodate a woman's height and shape, aiding in the prevention of cold spots and saving your body the energy of trying to heat uninhabited areas of the bag.

The Switch 35 Degree Women's sleeping bag is insulated with compressible, breathable and fast-drying Thermic MX synthetic fill. Unlike down fill, Thermic MX is water-resistant and continues to provide warmth even when wet. This is particularly important if you'll be camping in wet weather or humid climates.

The horizontal baffles of the Switch 35 Degree Women's sleeping bag ensure that insulation is distributed evenly throughout the bag. This design aids in the elimination of cold spots and provides consistent comfort. An insulated, contoured hood helps reduce heat loss and keeps your head warm and comfortable. A two-piece, draw-string adjusted draft collar keeps your face warm, locks heat inside the Switch 35 Degree Women's bag and prevents cold air from creeping inside. Enhancing comfort and warmth, Mountain Hardwear's patented Comfort Footbox creates ergonomic, insulated space for your feet.

Mountain Hardwear's Quantum expander is a zipper system that cinches down tight to take best advantage of the mummy-cut of the Switch 35 Degree Women's bag. By eliminating cold spots and keeping the bag snug against your body, this design provides optimal thermal efficiency and keeps you as warm as possible. Depending on conditions, however, this design can feel a bit stuffy, especially if temperatures creep high above the temperature rating of the Switch 35 Degree Women's bag. The Quantum expander can be unzipped, revealing an additional 8 inches of insulated material running the full-length of the bag. This extra fabric provides a bit more room to stretch and allows you to sleep a little cooler on warm nights.

The Mountain Hardwear Switch 35 Degree Women's sleeping bag is available in Reg (fits up to 5'5") and Long (fits to 5'10") lengths. Each Switch 35 Degree Women's sleeping bag includes a nylon stuff sack.
