Easily withstands lower temperaturesReview by Xavier
I used this sleeping bag on Denali, where we experienced nights with outside temperatures going down to -40°C (that would be about -25°C inside a 4-person tent with 3 persons). With two mats and a bottle of hot water inside my sleeping bag, I was almost too hot!
Definitely a great product. (Posted on 6/4/2017)
Tested to -48.5F with Great SuccessReview by Brandon Germer
To test my gear for Denali, I took my Peregrine out to the foot of the Knik Glacier in Alaska in February to a place with a microclimate known to have very, very low temps. I took a thermometer with me, and ate a frozen Subway sandwich I let freeze solid to simulate my body being at altitude.

I combined the bag with a Feathered Friends Icefall parka, Feathered Friends Volant pants, and Icebreaker base layers including a wool hoodie and vest, and had Feathered Friends down booties on.

It got down to -48.5 for about 5 hours, but I stopped checking for a bit because my eyeballs were freezing and I had to keep a couple hats pulled over my face.

Did I stay warm? You bet. Feathered Friends gear is top notch.

When I climbed Denali, it only got down to -22F at its coldest in June, and I only zipped it up all the way once.

Talk about bomb proof!!! (Posted on 2/28/2015)
Peregrine RocksReview by Peter
I used this bag on Aconcagua and Denali last year. I am about to use it on Vinson. And I plan to take it to Everest next spring. The bag is very warm and does everything that FF claims. Also, at 6'2&quot; and 200 lb., I appreciate a bag that is comparable in weight to bags that are more constricting, but can accommodate my larger frame. Well done, FF! (Posted on 11/4/2014)
Great cold weather bag -30FReview by Captain
I've had the bag for about two years and just this past week had the opportunity to sleep with it in -31F temps in Montana in a MT Hardware EV3 on a Exped Downmat. I was very warm. I suspect it would have been warm to -40. A great bag. Thanks for putting together a great product (Posted on 2/13/2014)
