Warm and lightweight for alpine ascentsReview by climbingchic
This is my go to sleeping bag for fast alpine winter climbs in High Sierras. Super lightweight and lofty. It does keep me warm to temperatures it says. If it drops overnight to 20F I am warm enough just to sleep in my underwear. The bag does get wet sometimes from condensation (if very cold outside) but it's never wet inside. It does dry fast if it gets wet. Another feature I like is that the bag is wide at hips and I can curl in my bag or cross the legs. My boyfriend is jealous of that :) because his bag is only wide at shoulders.

Can't believe that FF is pretty much the only company (so far I found) that makes QUALITY and lightweight sleeping bags for women. I like that they make short bags too so I don't have to end up hauling long sleeping bags which are hard to keep warm inside because of empty space. (Posted on 2/27/2018)
Perfect bag Review by adqak
I purchased the prior version of this bag in October 2013. It has been to Argentina, Patagonia / Chile, Iceland, New Zealand, multiple provinces in Canada, throughout Alaska and the PNW, and in the SW in the winter and fall. It is a perfect bag. It compresses small enough to take traveling and backpacking but is so comfortable it's better than a down blanket for truck camping. It is disturbingly expensive - but worth it over the long run. Currently, if you amortize the price over my use, it's been well under $5/night, and it still looks brand new. I do not purposefully snow camp, but have been caught in snow / frost / hail / below 20 degrees many times and have never been cold in this bag and almost always end up shedding my socks by morning.

Still great in the winter.Review by Em
It's mountain season now!
Just came back from an overnight in the Snoqualmie region, I think it was around 20F overnight, Slept in a 3-person 3-season big agnes ul tent in the snow. Just wore base layers in the bag, was very comfortable all night.

Strongly recommending this sleeping bag. It's light, warm and very cozy. The only thing that has ever annoyed me is that the zipper pull is really cold against your face (on the inside of the bag) if you happen to find yourself in such a position... (Posted on 4/10/2017)
Love itReview by Em
I got this bag at the beginning of the summer to replace a really old and clunky -12C hybrid bag I had from MEC. I rented from feathered friends last year and loved the bag I had then.

Haven't tested it in winter conditions yet, but the bag was pleasantly warm the whole way through a 6 day hike in northern Iceland. On warmer nights, I find it much more pleasant to wear some sort of long pj's with this bag otherwise I end up feeling quite clammy under it - even just as a blanket on top of me.

When I take this bag hiking, I stuff it into a 10L compression sack, which it just fits in.

I'll throw up another review for the winter mountaineering season! (Posted on 11/1/2016)
Love this bagReview by MP
I took this on a weekend trip where temps were only expected to be in the 40s. I'm a super cold sleeper so I wasn't worried that I'd be too warm. I've also learned not to trust the weather forecast for this area. Good thing too, our first night got down to 27F. I was in a t-shirt and shorts and slept like a baby. It's light, warm and the grey color is definitely not the shouty colors women are usually forced to endure in equipment. A must for stealth camping when alone. (Posted on 4/22/2016)
