Snug And Warm

This sleeping bag is a thing of beauty. It is super warm and I love the way the hood cradles my head. It’s wide enough that I can turn over or sleep on my side without the entire thing turning with me. Bought it for a Kilimanjaro trip plus winter camping when my 20-degree bag won’t cut it.

12 Years With This Bag!

As a hitch hiker, wedding photographer, and landscape photographer, this bag has taken me all over the US and never has left me cold. I’ve pushed many negative temps with this tent, in and out of a tent, and I’ve never been left wet or cold. Doubled up with some light layers and you’re ready for the apocalypse practically.

Wonderful Bag!!!!

Great Bag! have 2 of them - zip together for some love'n, though its been a while since she is an ex now - ; ))) - very versatile for varying temps/climates. Highky recommend if you are looking for an amazing and versatile bag. Very high quality - very worth the "chaching"

Superior Loft In A Shorter Package

What o love about this bag is that it’s short (I’m 5’6” and so is the bag) BUT it’s wide enough for extra layers or to throw electronics or a hot water bottle inside. It’s still lofty and lightweight though. I haven’t put it to the limit though it’s kept me warm below zero. I’d say the construction and fabric is tougher than my other bags from FF and montbell

Excellent Bag

This has been my late October Elk camp bag for the last 6 years. We spend the week at 10,000. While we never know the temp other than real cold and cold my partner in his 25 below synthetic bag regularly is cold and restless in multiple layers, while I sleep in just a base layer or less with no problem other than getting too hot. Ground cover is obviously important but for the job the bag does it's worth the bulk. I used to freeze my a@# off and finally pulled the trigger on the bag and I have been warm and cozy since.
