Ski touring and mountaineering demand a down sleeping bag that is comfortable in the coldest months of the year. The Altair sleeping bag is designed to provide efficient warmth down to 0F (-18C), while offering light, packable performance that makes each day in the mountains more enjoyable. Like all Therm-a-Rest sleeping bags, it integrates with your mattress to eliminate the sliding, twisting and cold spots that can interrupt sleep.
