Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.

Durability issues. Lamina welds fail.
8 months ago
Keep your money. My Lamina kept me warm down to around 50° F. The Lamina welds all came undone through normal use and the inner lining tore for no apparent reason. The welds coming undone was the biggest disappointment. It’s as though double sided tape was used. On the plus side, however, the bag draped well and was very light. I’ve had this bag for almost 3 years and used it intermittently in warmer weather.

I would like it to zip lower to let my feet out
1 year ago
It only zippers down to about your knees. My feet tend to get hot and it makes getting then out of the bag difficult and vice-versa if I start out hot and get cold during the night. My fault that I should have read up on it more before the purchase. But I borrowed a friend's Lammina 35 and it zipped to about the toes and I just expected the 30 to be similar.
