Yes, this is a great sleeping bag for cold-weather camping. The Alpine -40° bag features a high-lofting down, technical hood, oversized draft tubs, and draft collar to keep you warm on the coldest nights. And, Alpine -5°F is designed for the extreme cold of alpine expedition use. We recommend Ascent/Altitude or ultralight Spark/Flame sleeping bags for occasional cold-weather use..
