Gear Review: Feathered Friends Peregrine eVent Sleeping Bag

Packed with 850-plus-fill down, this bag lofts up a full nine inches, yet remains remarkably packable.

Heading into polar bear territory? Get peace of mind with this bag. “On winter bivies, you typically feel pretty exposed and insecure,” says a tester who slept through gusts that nearly blew him off his pad, with windchills down to -30°F. “But this bag was like a force field that made the events of the outside world seem of little concern.” Packed with 850-plus-fill down, it lofts up a full nine inches, yet remains remarkably packable for its class—about basketball size.

A waterproof/breathable eVent shell keeps the down bone dry—even when puddles of tent condensation pooled on the bag’s foot end—and a two-inch-wide zipper flap prevents blowing moisture from penetrating. The hood has a reverse-differential cut*, so it surrounds the head like a customized cloud of warmth. Bonus: The roomy fit accommodates layers of puffy clothing that could push this bag’s comfort range down to about -40°F.  $759; 3 lbs. 14 oz.; -25°F

*Reverse-Differential Cut Hood Fabric is cut larger on the inside than the outside, leaving room for the down to expand inward and fill in space around the head.
