User Review: Mountain Hardwear Lamina 0°
Source: bought it new
Price Paid: $130
Great affordable bag.
I have the 2012 version of this bag. I have used it camping 3 times this winter. This bag is pretty warm. I haven't tested it down to 0 degrees, but I have been warm at around 10-15 degrees. It is comfortable and I have not noticed any cold spots, even when I roll onto my side to sleep.
I have read about people having zipper problems, but I haven't had any yet. The insulation is really soft and lofty for synthetic and packs down pretty small also. I bought this on sale for $130 and feel like it was a really good deal.
