Mountain Hardwear Lamina 0 Sleeping Bag

I just took this trekking in Nepal for 16 days and was quite toasty down to 10F inside the tent at the coldest (at about 4000 meters). It did a much better job than my old down bag on the warmer nights (half zipped) keeping me at a comfortable temp, too (not half too-warm, half too-cold). I have no doubt I'd be comfortable past 0F in it. Kudos to MHW for including the compression sack and storage sack. A little more head room might have been nice for my pillow, though (we had porters). I have the long version, and it was really nice to have the extra room for a set of clothes and some small battery operated gear (I'm only 5'9") kept warm for the morning in the bag. We had some wet spots on the bags a couple of nights, but no cold spot on the inside I could detect. Compresses well (down to about 10"x12" easily) and is fluffier than I would have expected from synthetic. My wife had an REI Zenith -5 and was comparably warm, though for the same $ her bag is a lot heavier, and doesn't pack down nearly as small (and didn't come with a compression sack). I'd buy this one again without reservation, planning to continue using it as my car or without-a-tent bag.

I like this bag. It replaces a 20 degree North Face Cat's Meow. It has significantly more wiggle room, particularly around the shoulders. Plenty of room to turn over inside the bag, whereas the Cats Meow was kind of tight. It's really soft too, and compresses down as small or smaller than the North Face bag. Pretty good considering the Lamina is rated for 0 degrees and the Cat's Meow is rated for 20.
Most of my trips are in the 10,000 ft + altitudes of the Sierra Nevada mountains, and the Cat's meow usually let the cold seep in later in the night, even though I use a silk bag liner, which is supposed to add 10 degrees. I had no such problem with the Lamina. I slept warm all night (temps in the mid 20s) without even covering my head with the hood.
The neck and face gasket work perfectly to block out the drafts that were always annoying with my old bag - very nice feature - probably my favorite part of the new bag.

This bag is honestly just plain awesome. I was wary about a synthetic bag at first, but after trying out the lamina, there's definitely no need to be. The Thermic Micro insulation is truly amazing stuff. I can pack this bag down with a compression sack smaller than almost any other synthetic i've tried, most of them with warmer ratings! As for the warmth, very impressed. I naturally sleep warm, and it's definitely subjective, but I used this bag at an MTB race last fall where we got frost overnight and had a comfortable sleep, despite forgetting my thermarest! And I was in a 3-season tent that was mainly mesh! Very impressed by this bag. The other day as I was uncompressing it for storage i noticed it even has a little internal pocket at the chest for glasses/contacts/lights! Beauty.

Warm sleeping bag for cold, high-altitude nights, as long as you wear one or two thin layers. Used it on Mt Whitney Trail Camp and whilst climbing Mt Langley's, camping on both peaks at 12000ft with temperatures going down to -5C. I'm a VERY cold sleeper, so I imagine most people will be toasty in this one. Very nice for the remaining, low-altitude nights I used it. Very soft, generous cut with plenty of wiggle space inside, very nice feel to it, compresses easily and fits well into rucksacks. Considering my needs (mostly late fall and winter, low-level valley camping with the occasional high-altitude, below-zero nights)it's a very good deal under $200. Highly recommended. For colder environments consider something beefier.

For the price this bag is great. Works great for backpacking and car camping. I just got back from a week long backpacking trip to canyonlands utah, night got down to high 20's low 30's and the bag kept me very warm. It packs down great, is not heavy at all and comes in a stuff/compression sack, for easy transportation. Also it comes with a storage sack so you don't really have to hang it up. The ripstop material really works, and the "no-seems" feature is nice. Overall I'm very happy with the bag

I love this sleeping bag. I bought the short one designed for a person under 5'6" and used it in Peru while on a trek. I found it very comfortable, warm and very light to carry around. I was able to easily attach the sleeping bag to my pack by using the straps on the compression sack that came with the sleeping bag. It's a great color too. I can't wait for the chance to use it again.

Recently purchased for my son. Used on 3 day camping trip. Nightly temperature about 25 degrees. He was plenty warm throughout night while I froze in my old 25 degree bag.

Bag material and construction are excellent. Included compression stuff sack as well as a loose home storage sack.

Plan to buy one for myself now.

i rarely use a tent and as such have put this bag through some serious weather... it's been poured on all night, made it through snow storms and has lived up to its 0 degree rating... i've had the bag totally soaked and have been warm and slept through the night no problem. awesome price for the quality
