Although the design is somewhat radical compared to what we think of
as a sleeping bag, I have quite possibly found my ultimate ground/
hammock sleeping "bag" in the Bozeman Mountainworks Quantum Arc
Variable Girth Sleeping Bag. Very high quality. Pertex Quantum
fabric inside and out, a unique tappered baffle layout that goes
from 2" at the neck to 3.5" at the feet. No hood (use your warm
hat), no bottom , though the design does wrap round the shoulders
well. High count down fill. About a pound total weight.
As for a temp rating, BMW doesn't rate their bag, but depending on
who you trust I've seen bags with a 2" loft rated to 20 degrees (
Ray Jardines' ETR system) and the very similar Nunatak Arc bags 2"
models rated at 32 degrees. By the way, Nunatak builds the Quantum
Arc for BMW.
The nice thing about this Variable Girth feature is that you can
wear additional clothing inside the bag, but by utilizing the girth
adjustment feature, still make plenty of room for yourself without
compressing the bags loft. With my Golite Coal jacket on, it becomes
my winter bag.
But I've rambled on enough.
