Gear Review: Brooks-Range Elephant Foot Sleeping Bag

Pair this bag with a puffy jacket for an ultralight, ultratoasty setup.


Attention alpinists: Serious about saving weight? Consider this: You already have a puffy belay jacket with you, which can serve as a sleeping bag for your upper body. For your lower half, slip into the Elephant Foot, a chest-high, zipperless bag that weighs only 15 ounces. With an ultralight 15-denier Pertex Quantum shell and 850-fill down, it packs down to the size of a football even without a compression sack.

The Foot has elastic drawcord suspenders (wear them under your jacket) that keep it from sliding down during the night; another elastic drawcord closure helps it to seal around your body for a draft-free night. Pair it either with your own jacket or with BR’s Alpini Mountain Anorak Hoody ($264). One tester loved the Hoody’s insulated kangaroo pocket, which kept his hands toasty, and side zippers that allow ventilation. Obviously, this system requires a minimalism-at-all-costs mentality.

One tester spent an open night getting raked by subfreezing winds above 12,000 feet and said: “It wasn’t the best night I’ve ever had, but I stayed warm enough to get some sleep.” Another braved single digits and wrote: “I’m not tough enough for hours of shivering—some may be, but I’ll stick to the 20s and up.” $249; 15 oz.; one size;
