SLEEK SLEEPERMountain Hardwear welded bag-length sheets of its new Thermic CF insulation inside a nylon sandwich to make a uniformly warm 15-degree sack that’s compressible and affordable. On a late-season attempt on the North Cascades’ Liberty Bell Mountain, I clunked into camp with frozen toes, easily shoved my size-12 feet into the big footbox, and felt my piggies warm right up—and stay that way as temps dropped into the twenties.
Bonus: Big cinched collars arrest drafts.
Bummer: Three awkward pockets, instead of one good one to stash a watch in.
