Snow Goose EX -40 Sleeping Bag

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.

EX: Winter & Expedition. Pertex® Shield® fabric. 15 denier with 40 denier rip-stop reinforcement. Water-resistant/ breathable.

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

Stay warm and toasty all night.Review by Friendly Arctic Adventures
I am a guide and a dog musher in Alaska. I spend a lot of time and nights outside in the winter, many times without a tent. The Snow Goose bag is my security blanket for when things get nasty or I'm wet, cold and tired. I've owned my original bag for ten years and it is still doing it's job. Can't say that for my North Face Darkstar bag. I've had it cleaned a few times to fluff back up the fill, especially on the back of the bag. If I'm on a thermarest and I've got this bag, I don't have much of a worry in the world. I now own three of these bags for myself and clients out on trips. It's an investment for sure, but one that you really can't put a price tag on when you want to be warm at night. (Posted on 11/17/2017)
