The Snow Goose is the world’s premier high altitude expedition sleeping bag. This model shares many design elements with the warmer Snowy Owl but delivers superb warmth at a lighter weight. We eliminated the second (inside) zipper and scaled back the hood and shoulder regions, but retained the efficient contoured shape that keeps full loft of the 900+ fill down around the head for maximum warmth in some of the coldest places on the planet.

The new, highly breathable Pertex® Shield Air panel is strategically located to help more moisture to vent. 

ES: Winter & Expedition. Pertex® Shield 15 denier with 40 denier rip-stop reinforcement fabric with water-resistant/ breathable coating with 3 Layer Pertex® Shield Air electrospun laminated fabric. 

Ideal for: High-Altitude Expeditions, Frigid Winter Camping, Polar Trips

Customer Reviews (4.6 / 5 · 5 reviews)

Sophia B. ★★★★★

Last weekend in minus 30, I stayed perfectly warm all night and the draft collar really locked the heat in. The zipper didn't snag once, which surprised me after some other bags I've used.

Joseph S. ★★★★★

I've been using this on multi-day winter expeditions, and the baffle design really keeps the down from shifting even when I'm tossing around. The zipper glides smoothly without snagging the fabric, which is a huge relief in freezing temps. It's been my go-to for sub-zero bivouacs.

Hannah ★★★★★

Took this out for a night at 14,000 feet and stayed perfectly warm despite the wind. The draft collar cinches down tight without feeling restrictive, which made a huge difference for comfort.
