Product Highlights

The innovative Therm-a-Rest Altair 0 Degree sleeping bag utilizes high-loft goose down and a ground-breaking design to deliver cold-weather performance at a backpacking-friendly weight and packed size.

With 40 years of experience building sleeping pads, Therm-a-Rest has an extensive background on how sleepers sleep. This wealth of experience has led to the development of the Therm-a-Rest sleeping bag, a unique offering that utilizes zoned insulation and Synergy Link mattress connectors to keep the bag properly connected to a sleeping pad (sold separately). Based on thermal mapping, insulation is concentrated on the top of the bag and used sparingly on the sides and bottom of the bag. With an assured connection point between the bag and the pad (up to 25" in length), warmth is directly provided to the sleeper by the R-value of the sleeping pad. A contoured shape provides room at the torso to move around while tapering at the feet to improve thermal efficiency. NOTE: Unlike traditional sleeping bags, there is little to no insulation on the bottom of the sleeping bag.

The Altair 0 Degree bag is insulated with 700+ fill goose down. Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel and, despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet. Therm-a-Rest minimizes that risk by applying a DWR finish to the Altair 0 Degree bag’s 30D Nylon Ripstop face fabric.

Eliminating cold spots and providing comfort, baffled construction ensures that the insulation remains effectively distributed throughout the bag. A contoured, ergonomic hood helps reduce heat loss and keeps your head warm and comfortable. An insulated draft tube sewn behind the snag-free zipper keeps cold air from reaching the inside of the sleeping bag.

The Therm-a-Rest Altair 0 Degree sleeping bag is available in Regular (fits up to 6’ 0") and Long (fits up to 6' 6") lengths. A stuff sack and storage sack are included.
