The Super Down Altai is a 15°F down backpacking bag built for cold-weather hunts and expeditions. It uses water-resistant Quixdown goose down, an aluminized lining that reflects body heat, and a baffle layout of chevron horizontal and vertical box baffles to stop down migration and cold spots. Draft tubes at the head, shoulder and zipper add warmth, and the cut gives extra chest room for side sleepers. It competes with other ultralight down bags on warmth-to-weight, with the reflective lining and treated down as its main edges.

Rated 4.8 out of 5 from 38 ratings, owners largely praise the warmth, light weight and packability for cold hunts. A few note the bag is best treated as a 15°F bag, not a deep-winter one.
The Super Down Altai 15° Sleeping Bag is an ultralight, packable sleeping bag built for expedition backpack hunts. It is insulated with Quixdown® made from premium Eastern-European goose down. The down is treated with a DWR finish so it resists wetting out, including in the IDFL water-shake test.
The interior is made from an aluminized fabric that reflects and retains body heat. The outer shell is a lightweight, 100% windproof fabric with a K-DWR® water-resistant finish. Chevron-shaped horizontal and vertical box baffles keep the down from shifting and migrating, which eliminates cold spots. Draft tubes around the head, shoulder and zipper add heat retention and comfort.
The bag weighs less than the previous design and has extra room in the chest area for side sleepers. A zip-in expansion wedge adds more space and is sold separately. On warmer nights, the bag can be unzipped and used as a quilt, with feet in the ergonomic, generously sized foot box.
