Women are not shaped the same as men; as the Black Eyed Peas so poignantly croon, they have "lovely lady lumps, in the back and in the front." The sleeping bag designers at REI listened, and as a result their women’s Kilo series bags showcase a number of hump-specific features.
The women’s Sub Kilo is comfort-rated at +15F, and since women generally sleep colder than men the 750-fill down is heavier in the contoured hood and roomy foot box. Quality touches include a nice lightweight compression sack, inner zippered pocket for small items, full-length zipper baffle and loops to tie into a sleeping pad.
There are just two drawcords, one for the neck and one for the hood, running through a single cord keeper; to tell them apart by feel in the dark one is flat and one is round, an elegant solution. The bag is certified velcro-free; no snagging on your long underwear. It’s available in two sizes, regular (5’6" women) and long (up to 6′ Amazon women; call me now). And the best for last: it weighs under two pounds! Also available in -5F and +35F ratings.
