    Feel the fire after a cold day.

    The Lamina Z Bonfire Sleeping Bag is Mountain Hardwear's warmest synthetic bag, built for winter camping trips in the alpine. Its unique Lamina construction welds the water-resistant shell to Thermal.Q insulation for better protection against moisture. Zoned insulation places more warmth where you want it, and less where you don't need it. Every bag in the Lamina collection is lighter and more compressible than other down bags of the same temperature rating.

    Mountain Hardwear cut the Lamina Z Bonfire into a slightly wider mummy shape to better accommodate expedition clothing. Despite its wider fit, the Bonfire has a snug, tailored hood with a face gasket to protect your head from harsh winds. It has an ergonomic draft collar down the full-length zipper, and the footbox is bigger for more comfort.

    Very warm.

    • Familiarity: I've put it through the wringer

    This bag is, as others have stated, a little on the heavy side and bulky even when compressed down as small as it can go. For winter backpacking, you'll need a very large backpack, and it will take up most of the space inside of it... But it's worth it because the bag is very warm and cozy. For the price, this sleeping bag is highly recommended. I think that the advertised temperature rating is accurate.
    I've been camping since buying it several months ago, and have been very warm every night, even through the snowy parts over Christmas and New Year, here in Salt Lake City, Utah.

    Tried 5, Picked 1

    • Familiarity: I returned this product before using it

    Okay, so my review is based solely on "fit" for a tall guy. I bought five winter sleeping bags to test- feel, comfort and dimensions and how durable the materials "felt". In the end I kept only 1 (Marmot CWM). As I sent the 4 others back and did not try them in actual sleeping situations, I cannot comment as to their performance in cold weather- only fit and initial comfort for a 6'6" guy who weighs 215 lbs.

    Okay, in terms of value (Bang per $), this is probably a 5 star bag. If I was more price conscious, I would have gone with this bag. Overall, felt like it would be warm, it was well constructed. Would have been nice had it been an inch or two longer, but most people aren't 6'6", so hard to cut them on that. A little narrow in the shoulder area if you've got wide shoulders like me, but overall, for the price, I would say this is going to be a great sleeping bag. It did come with a compression sack and I was able to get it down fairly small, but it's not going to fit in the bag compartment of a back pack, though good luck getting any subzero sleeping bag to fit there. This packs down to a size bigger than it's down counterparts, but for a couple of inches and maybe an extra pound, if $400 matters to you, that's how much you'll save by going with this bag. I didn't go with this bag, because I liked the comfort of the Marmot bag a bit more and I am not real price sensitive.
