Yep, that is my guest bag, but I am a larger guy and prefer the roomier non-arctic version that I kept when I left service in the 1980s, I use blankets inside for super cold weather, or a cotton sheet to moderate my temps during warmer weather.
It is a fantastic bag, but too heavy for backpacking of course, (except in the Army) that little hole to breath out of is nice and keeps your face warm while keeping moisture out of the bag and the zipper is without equal.
I have probably 10 various sleeping bags to choose from that I own, and that one is my favorite.
More bags should have the zipper down the center instead of on the side.
