Am selling my retangular Marmot winter sleeping bag for $200. This bag, which is no longer made by Marmot, has a shape similar to the Western Mountaineering Tamarak sleeping bag. It's dimentions are very similar to their regular length Alpinlite sleeping bag (which I own and compaired the Marmot to). This Marmot bag also opens up like a quilt. Opened up and flat, it measures approximately 76 inches long, 38 inches near the foot, and 57 inches at its widest point. I also bought and have a seperate hood, included, that could be sewed on to the bag if you are also tall.
The bag was rated by Marmot to be a 5 degree bag but using Western Mountaineering as a guideline I would suggest that it is truely a 10 degree bag as it lofts better than my over-stuffed Alpinlite. I have slept comfortably in this bag down to zero degrees with some cloths on. The bag is in excellent shape; it is clean with no rips. I slept in it a dozen times at most and always stored it properly. I believe, but don't know, that the outer shell is GTX. In any case, the outer shell is very smooth.
I envision that the bag and hood would accomodate an individual of 240 pounds and up to 6 feet 4 inches tall. I am selling the bag because it it highly unlikely that I would ever use this bag again because of my family obligations.
