Daniel W.wrote a review of Marmot Alpha Sleeping Bag: 30 Degree Down on July 3, 2014
This bag is the real deal. It's super lightweight, easy to operate, and of course, very comfy and warm. It also comes with a mesh bag and a smaller compression sack. Compared to the Never Winter, this bag is lighter due to the 700-down, therefore also (probably) warmer even though both are rated at 30F.
This bag is awesome, get it, you won't be disappointed.
