The Flame™ Ultralight Women's Sleeping Bag Series spans everything from an ultralight down-filled liner to a mid-winter fast-and-light sleeping bag. Each model uses premium materials and no-frills design to provide cutting-edge performance for the designed end-use.
The women’s specific mummy fit is narrower at the shoulder and wider at the hip, and features extra down compared to the unisex Spark models.
Is this women's down mummy sleeping bag…?
Suitable for cooler temperatures? Yes. You would want the Flame 15°F or possibly the 25°F – either mummy sleeping bag will work in late Fall, the 15°F will take you down to early winter temperatures when paired with an adequately insulating sleeping mat.
Really suitable as a sleeping bag liner? Yes. You could use the Flame 55°F, or even the Flame 48°F or 35°F to boost the performance of a bag for cold-weather use. Adding one of these to a 20°F / -5°C sleeping bag might make more sense than buying a “0°F / -20°C” sleeping bag for occasional winter use.
Able to be zipped to another sleeping bag? No. Even though the 25°F and 15°F have full-length side zippers, they are not designed to be coupled to a sleeping bag with a left zipper.
