The Western Mountaineering Bristlecone MF -10 Degree Sleeping Bag is a spacious sleeping bag for winter exploration. Rated down to -10°F, if the wind is howling and snow blowing outside your tent, you might as well climb inside and revel in the warmth of 42oz of 850+ fill power down. It's baffles are packed so full you're getting an 8.5" loft, but incredibly it still only weighs 3lbs, 15oz. It features two zippers so you can zip it together and snuggle close with another or lie it out flat in weather that is warmer. Quality, made in the USA craftsmanship, sweet.
