  1. Tested to -48.5F with Great Success

    by Brandon Germer on Feb 28, 2015

    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!!!
  2. Peregrine Rocks

    by Peter on Nov 4, 2014

    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" 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!
  3. Great cold weather bag -30F

    by Captain on Feb 13, 2014

    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
  4. Great Bag

    by Matthew on Jan 12, 2014

    Love the Peregrine! It is such a warm bag. I wanted to see how waterproof it was and I tested it by pouring a cup of water on it and it just beaded off. The only downside to this wonderful cocoon is that there is not a pocket. I also love the fact that it's made in the USA.
