This is a great bag. The lightest 20*F bag I've owned. It weighs 1lb 14.5oz. It is 1.5oz over spec., but I suspect that that 1.5oz is down and the reason why this lofts more than the 5" that it's spec'ed at.
Made with a Pertex Quantum outer shell and a 22 denier lining. It feels great against the skin and is suprisingly strong.
The bag has a 24" chest zip that vents well and allows me to wear the bag and use my arms at the same time.
The FootVent works well. There is no accidental opening of the vent and it seals up completely and doesn't leak.
The hood comfortably wraps my head and creates a breathing hole right at the mounth.
The quality of the stitching is topnotch.
Uses 800 fill down and lofts to 6". It actually is more like a 10-15*F bag. The girth at the shoulders is 60" and it is 72" long. I can use it from about 30*F and below. Above that and it is too warm.
I've had it down to 13*F with my base layer top, softshell pants and wool socks and was toasty warm in a 3 season tent on snow. I've also had it at 23*F not in a tent with just a tanktop, wool socks and wool boxers on and was toasty warm.
There is enough room inside for me to wear insulating top and bottoms without compression.
This is a very sweet bag.
