- MMikeVerified BuyerRated 3 starsNov 30, 2022Great bag poor sack
I was very happy with the bag and it was too warm at 48 F . However the compression sack is very cheap and the bottom seam blew out. I contacted Teton and I am waiting over two months and do not have a repair yet!

I absolutely love this winter bag. Purchased in 2016 and still giving it a 5 star. Nice and warm. Packs down nicely and very comfortable. Slept in -40 in an MSR Hubba Hubba only in base layers. (I'm a hot sleeper my wife tells me)

This is the best sleeping bag I have ever owned. I took my mummy bag on an overnight backpacking trip in the high Uintas where temps dropped to around 48-50 degrees. As someone who is always cold, I was a little nervous about staying comfortable overnight, but this bag was so much more than just comfortable. This sleeping bag kept me cozy and warm all night long!

It's not called the mummy bag for nothing. You will literally sleep cozy like a mummy!
