The NEW Women's Torchlight series features an expandable panel to increase space up to 10 extra inches! Depending on your sleep style and body shape, you can adjust the bag for a customized sleep experience. Our Women's specific bags differ in shape and fill weight with a less drastic taper from shoulders, to hips, to feet - reducing cold spots and creating more warmth. Ideal for backpackers looking for additional comfort in a mummy bag but simple to use when car camping and catching z's at any campsite.
