Mountain Hardwear Bozeman™ 30F/-1C

The Mountain Hardwear Bozeman 30F/-1C is the lightest synthetic bag in the Bozeman line, rated 4°C comfort and -1°C limit — unlike the rest of the range, though, this is a manufacturer rating rather than an EN/ISO 23537 test result, so comparisons against independently tested bags should be read with that caveat. Its 830g of recycled Thermal.Q fill uses the same synthetic technology as its warmer siblings, just in a smaller quantity. At 1534g and 11.3L packed, the Bozeman 30 is a sensible pick for three-season camping where moisture resistance and synthetic fill's lower cost matter more than shaving grams — the comparably rated down Bishop Pass 30F weighs just 810g, roughly half as much. A two-way zipper with an insulated draft tube and coupleability with a second bag extend its use for pairs. A practical touch is the micro-fleece-lined stuff sack that doubles as a pillow, handy for camp trips where every gram isn't being counted. An internal length of 218cm and unisex cut to 183cm provide ample room.
