Mountain Hardwear Yawn Patrol™ 15F/-9C

The Mountain Hardwear Yawn Patrol 15F/-9C uses 650-fill RDS-certified down in a spacious semi-rectangular cut, rated by the manufacturer to -3°C comfort and -9°C limit. At 1255 g with 609 g of fill it sits between the lighter, higher-fill-power SE version and the heavier synthetic Mountain Hardwear bags — a mid-weight down option rather than the lightest or warmest in the lineup. Internal length runs 218 cm with 157 cm at the shoulder and 148 cm at the hip, generous for a bag built around sleep-position freedom. Dual angled zippers are the defining feature: beyond normal venting, they let the bag unzip flat and double as a quilt or camp layer, useful when a mummy's fixed shape isn't needed. The shell mixes 30D nylon ripstop on top with tougher 45D on the bottom, carries a DWR finish, adds foot box ventilation, and uses a simple drawcord hood rather than a fully adjustable one. A stuff sack is included; sizing is unisex up to 182 cm. It suits three-season campers who want a versatile, multi-use bag over a dedicated ultralight mummy.
