Mountain Hardwear Bishop Pass™ 15F/-9C

The Mountain Hardwear Bishop Pass 15F/-9C is a three-season down mummy bag, EN/ISO 23537 tested to -3°C comfort and -9°C limit — a spring-through-fall range rather than genuine winter use. Its 601g of 650-fill-power RDS-certified goose down sits inside a fairly trim shell: a 157cm shoulder girth and 135cm hip girth point to a snugger, more efficient cut rather than a roomy bag for restless sleepers. At 1060g and 6.7L packed, it's a solid but not ultralight three-season bag — comparable-rated competitors now often come in under 900g. The single-direction zipper (no second slider at the foot end) is simpler but offers less venting flexibility than the two-way zips found on the colder bags in the same line. A shaped draft collar, draft tube, and internal pocket cover the basics, and a stuff sack is included. The cut is men's-specific, sized for users up to 182cm tall.
