In conjunction with our down parkas and pants, the Peregrine can easily push beyond the -25 rating; perfect for alpine style expeditions in extremely harsh conditions, or some winter camping in Minnesota.

Feathered Friends Peregrine Rocks for Alpine Mountaineering

Took this up Mount Sanford in Alaska. Held its own in serious snowstorms, wind, and cold temperatures to 15,000 feet. Packs remarkably small for a rock solidly built bag. Feathered Friends has the corner on the market when it comes to serious mountaineering sleeping bags. I own the 30, 20, 10, 0, and -25 bags, and have my eye on the -40F now as well. You cannot go wrong with Feathered Friends. I often ask for one or two ounces of extra down in mine. You want Feathered Friends when you sleep in that tent in those conditions at altitude (see photo).

Feathered Friends Peregrine ES -25 Sleeping Bag Review
Matthew C.

We had a cold snap in Colorado over the weekend which allowed me to test this bag in the -20F to -25F range. I only had a base layer on and was toasty the entire night. The bag also does a great job of handling moisture. I had no problems with breath condensation getting in and the Pertex Shield Air panel does an excellent job of getting any perspiration out. I am almost exactly six feet tall and got the regular and Feathered Friends is absolutely correct to say it is the ideal size. There is plenty of space to both spread out and still stash fuel, boot liners, gloves, and clothes. The little zippered pocket is a nice bonus touch. This was my first Feathered Friends bag and I will definitely be coming back for more.
