Mountain Hardwear Lamina -30 Sleeping Bag: -30 Degree Thermic CF

This is a pretty nice bag for the money. The synthetic fibers do a pretty good job all in all when it comes to retaining body heat in your average winter temps.(keep in mind that often times that the ratings on synthetic bags are often lower than what they're listed as) It works particularly well in wetter rainy weather, and the bag is really one of the most comfortable I've ever used. but as the previous reviewer mentioned, I don't think I'd want to take this one on very many winter trips to higher altitudes. While I've been an advocate for Mountain Hardwear gear over the years, there are better winter sleeping bags out there. This bag is extremely bulky and doesn't compress very well at all, not to mention it is heavier than the average backpacker would like to carry. For these reasons, the lamina gets 3 stars from me. I like this bag very much for local camping trips during the winter where I'm not backpacking in, but that's about all the use this bag gets from me. My personal favorite is the North Face Hightail 15 degree down bag, down is usually the warmest option anyways.

I took this bag on a particularly cold wet night up in the Tetons in mid May, I was plenty warm and the bag breathed well...didn't get that clammy feeling you get with some bags. However, I am a little apprehensive about taking it into the mountains in the winter with sub-zero temps.
