Marmot Women's Teton 15° Sleeping Bag

The Marmot Women's Teton 15° sits between three- and four-season use, with an EN ISO 23537 comfort rating of -8°C and a -15°C limit. It's built with 850 g of 650-fill-power RDS-certified duck down treated with Down Defender, wrapped in a 20D nylon mini-ripstop shell with a 30D nylon DWR panel and a 20D plain-weave liner — about 1640 g total, packing to roughly 46 x 22 cm. The cut is generously proportioned through the shoulders and hips relative to other bags in the range, trading some packability for a roomier feel — useful for side sleepers. A fitted contoured hood, insulated draft collar and draft tube, and footbox ventilation round out the features, and the full-length dual-side two-way zipper vents from either end. Unlike some siblings, only a stuff sack is included, with no separate storage sack. With a fill efficiency of 1.76 and roughly 109 g per degree, the Teton 15° suits shoulder-season and cold three-season trips, sized for users up to 168 cm.
