Devin M.wrote a review of Mountain Hardwear Lamina 0 Sleeping Bag: 0 Degree Synthetic on March 4, 2013
I used this bag while on a NOLS trip is Patagonia for 3 and a half months and this bag proved to be anything but "0 degrees". Once the weather got below 20 I was cold. This bag also took a lot longer of time to dry after being wet compared to other synthetic bags.
However, this bag is very comfortable, moveable, and packs well.
