As good as it gets!
Feathered Friends was the first store I visited when I moved to Seattle in 2009. The quality and care that is put into the design and delivery of these bags was shared with me and I knew one of these bags had to be mine. Years ago I got a 20 degree Swallow and recently this 30 degree hummingbird. I can say, without a doubt, that this bag is amazing. It packs down very well, re-lofts very quickly, and definitely holds a true and accurate temperature rating. I recently took this bag down to 34 degrees with a light shirt and a hat and was toasty all night. Between the superior product and the amazing service, I couldn't recommend FF more! But this bag- you wont regret it!
Best sleeping bag in the world
I love it! Very comfy and light weight. I am a slender 1.71 meters guy and it feels exactly the size for me. Nit too roomy and not too snug. As an example, I can't sit inside with my legs crossed baut I am allmost there a bigger sleeping bag would be an overkill gir me.
This is a great sleeping bag, and clearly a step above what around 400/500 gets you in REI. It is very very warm, warmer than the rating would suggest. It’s the puffiest bag I’ve had. I’d probably go for the 30 instead of the 20 if I was to do it again. I run cold and the 20 is too warm as a three seasons bag. It is very light, but the size may give you some trouble if trying to UL with a 40L pack. I have the hummingbird, I’m a pretty slim guy and find the bag plenty roomy even for side sleeping.
Great light weight bag
This bag feels great and packs down small. I was able to really squeeze it into a 6l compression sack and get it to the size of a nalgine. Very warm and comfy
