When you need to stay warm in humid or dewy climates, high-performance insulation is only half the battle; protection from rain, wet weather, and condensation is the other half. The Marmot Sawtooth Membrain Sleeping Bag flexes both the heat-retaining power of down insulation and the moisture-stopping power of a waterproof breathable membrane. Big brother to the water-resistant Sawtooth sleeping bag, the Sawtooth Membrain is Marmot's 15-degree, 650-fill sleeping bag option for wet-weather three-season backpacking or camping. The mummy-shape cut results in more room to move at the shoulders and a roomy trapezoidal foot box near the feet. Features like the Nautilus, five-baffle hood, ground-level seams, and internal stretch baffles give this bag a step up in comfort from a bag like the Trestles or the Rockaway. And while 800-fill and even 900-fill options exist in this same temperature range (the Pinnacle and the Plasma, respectively), the Membrain sleeping bag offers an ideal balance of warmth, weather protection, weight, and value. 

  • EN comfort-rated at 30° F (average women's comfort level) and lower limit rated at 19° F (average man's comfort level)
  • 650-fill down compresses well, rebounds nicely after repeated compression, and features a high warmth-to-weight ratio compared to synthetic fill
  • Mummy shape matches the natural contour of your body, keeping insulation closer at the feet and giving you more room to move at the shoulders
  • Membrain shell technology uses a waterproof breathable membrane to allow sweaty moisture to escape from the inside out, away from your body, while simultaneously keeping you dry from rain and moisture in your environment
  • Water-repellent, windproof, downproof nylon shell delivers lightweight performance without sacrificing durability
  • Down-filled draft collar, full-length draft tube, and ground-level seams help retain your body warmth
  • Stretch tricot baffles allow the bag to be stuffed and unstuffed without creating a tear in the baffle material
  • Nautilus 5 baffle hood surrounds your head with warmth, Face Muff allows you to cinch hood tight without irritating your face
  • Hood Muff and hook-and-loop-free Face Muff keep your face warm at night without irritating your cheeks, chin, or neck with a drawcord or rough closure material
  • Classic trapezoidal footbox gives your toes plenty of room to wiggle, heater-pocket in footbox lets you pack in some additional warmth
  • Two-way locking zipper design incorporates a guard to keep the zipper from getting caught in the zipper tube, a zipper tube to keep cold from leaking in at the closure, and a zipper garage to keep the zipper tucked away at the top or bottom of the run
  • Two hang loops give you attachment points to hang this sleeping bag to let it air out at home or in your garage
  • Stuff and storage sacks included
