Therm-a-Rest - Altair (Fall 2014)

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.

The Altair sleeping bag is extremely lightweight, highly compressible and warm enough to perform in the mountains all year long.

Therm-a-Rest is confident that when you sleep in one of their bags, you’ll wake up feeling better than ever. If you are not completely satisfied with your Therm-a-Rest sleeping bag, we will give you your money back—no questions asked. Return your clean, undamaged bag or blanket within 90 days and receive a full refund.
