"A sub 3 lb bag (2lb 15 oz manufacture listing, haven't personally weighed it yet), made of their Stretch technology that allows you to roll around in the bag a little more easily. Good for shiftier sleepers who like to get on their sides when they sleep as well as back.
Toasty and versitile. The continuous baffle allows you to shift the down around where you want it -- more on top for when it's colder and more underneath in warmer weather. Or from head to foot and vice versa.
I think the draft tube is a little on the slender side but not terribly so. I've been thinking of having it beefed up a little. It does have a strip of thicker material sewn where the draft tube comes into contact with the zipper, stopping snags.
There is no neck collar, which is fine since it's only a 15 degree bag. I've defeinitely had it down to that (with a pair of middleweight undies) and I like to sleep under the stars, so it's had plenty of exposed nights. There are two separate pulls on the hood, one for the forhead and one for under the chin/nose. Seals up nice and tight and can become a furnace.
The nylon shell is nice, resists moisture and looks very treatable with a repellent once the DWR starts to crap out. Stuffs to the size of a small loaf of bread and is mateable. YEAH BABY, GRRRRRR!
A great down bag for $200."
