Snowy Owl EX -60 Sleeping Bag

The warmest sleeping bag on the planet, the Snowy Owl has been the bag of choice for polar expeditions since its inception. Our fully contoured design maintains full and even loft of the 900+ fill down in the head and shoulder regions. A second inner zipper running parallel to the main zip keeps the differential cut at a constant thickness and guarantees a tight, even draft seal. This system also serves as a backup in the event of a zipper failure; a deadly proposition at 60 below zero. The only complaint we hear about the Snowy Owl is that “it was too warm”. Well… that’s the idea. If you’re chasing the coldest temperatures in the world, this is the bag for you.

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

WinsReview by Absolute Zero
I don't even use a tent with this. Had it in 40 below with high winds, climbed in. Layed there for 12 hours warm, while the blizzard passed. It's kind of embarrassing how awesome this bag is. People think you're showing off. (Posted on 2/20/2019)
-40 Snowy owlReview by Yukon
Ok, now I have a -40 snowy owl and I'll tell you what, I live in Alaska and at 40 below zero I can lay my ground mat on concrete with this bag and wake up 8 hours later warm. The best bag made today. (Posted on 2/26/2018)
Beautiful.Review by MP
Actual outside detentions for long: 92" long x 32" wide x 15" high. I did get 4oz extra fill. I have, over the years, had two TNF -40 Inferno bags. They were phenomenal bags. I have read, but never seen, the Snowy Owl. I felt like I was going out on a limb going away from what I've used and know, but I'm glad I did. The Snowy O, as I now call it, is clearly an exceptionally well-made bag. This maybe the last bag I purchase. I love it and I don't fall in love easily. Just make sure it's going to fit in your tent or bivvy. Plus FF was very thorough. (Posted on 2/28/2017)
Best Bag ever BuiltReview by Alaskaspike
The Snowy Owl is the Best Sleeping Bag that has ever been made. From Woods Eiderdown pre 50's to Kara Koram in the 60s which were great when I was younger.
Now with Reynauds and age this bag is without question the very best. Double zip. Closures, size, quality down. I live in the coldest inhabited community on the N. American Continent and have slept in the Owl at 58 below (no tent outside) and was comfortable. Usually sleep warmest without underwear or clothing, But will use down underwear and a hand warmer in each sock to get warm now with the reynauds. Once warm I stay warm. Feathered Friends have the best products I have seen in the Arctic and Sub Arctic here. (Posted on 5/31/2016)
