Swiss wrote a review of Mountain Hardwear Lamina 35 Sleeping Bag: 35 Degree Synthetic on January 11, 2011
I have to be brutally honest on this bag. Mountain Hardwear is generally my go to brand for quality, but this bag did not stand up to any test. I gave it two chances and on both occasions the Lamina failed to keep my warm. On both trips the temperature was around 40F and at the lowest 35. I found myself on both occasions having to boil water and storing it in a Nalgene for extra warmth to maintain some small bit of comfort. I plan on returning this bag well before my next trip.
Best part of this bag: Stuff sack was great. Storage Sack comes with me on all trips simply to store other items.
I would not recommend this item to a friend or even foe.
