Just got this in the mail. Can't wait to try this for my trip to the Kings Canyon. From my initial observation, these are few things I noticed. I am 5'8 about 165lb. The length for Reg is just about perfect for my height, but if I was any taller, I would def. go with the larger size just because when you try to huddle yourself completely from head to toe, reg. size is a bit tight.
In terms of girth, its kinda narrower than I hoped. Not enough material to be completely free and mobile underneath. I could see lots of potential cold spots and air coming in once I start moving from my original sleeping position. From what i see , I don't see how much more freedom one can have to move around underneath this than say other traditional mummy bag.
With this said, I could see there many be some tricks to using this bag. Anybody interested in chiming in?
