Mountain Hardwear Women's Bozeman™ 30F/-1C

The Mountain Hardwear Women's Bozeman 30F/-1C is a synthetic mummy bag rated to a comfort temperature of 4°C and a limit of -1°C under EN ISO 23537 testing — solidly a warm-weather three-season bag for spring, summer and early autumn rather than shoulder-season cold. Thermal.Q Recycled insulation fills a roomy women's-specific mummy cut, and at 1188 g it sits in a middle weight range typical of synthetic bags in this class. A wrap-around footbox vent is a notable feature, letting hikers dump excess heat on warm nights without fully opening the zipper — useful given the already mild rating. The full-length, dual-slider zipper along with a draft collar and tube add versatility for venting from either end while still sealing out drafts when needed. The 75D polyester shell and liner favor durability over minimal weight, consistent with synthetic construction generally. A fleece-lined, reversible stuff sack that doubles as a pillow is a practical touch for camp comfort. Overall, a warm-season bag suited to backpackers who want reliable, low-maintenance insulation for mild nights rather than technical cold-weather performance.
