The Mountain Hardwear Lamina 0-Degree Synthetic Sleeping Bag keeps you cozy during cold, wet winter camping trips. This roomy mummy bag with a shaped footbox won’t give you nightmares of being restrained in a straight jacket, and the Thermic Micro fill provides lightweight, packable insulation that won’t lose its loft after the first wash cycle.

  • An EN lower-limit rating of 10° F means that this bag is best used for shoulder-season camping in the mountains and for occasional use during cold winter conditions
  • Thermic Micro synthetic fill traps in warmth, keeps you warm even if it gets slightly wet, and compresses well for easy packing
  • Lamina construction means that the junction of baffles are welded, not sewn, for maximum loft and heat retention
  • Durable, lightweight nylon shell features a DWR treatment to repel frost, condensation, and dew
  • Soft polyester lining wicks away moisture
  • Face gasket and hood block drafts at the hood opening and seal in body heat
  • Full-length, two-way #8 zippers extend all the way to the footbox to allow maximum ventilation or the option to use the bag as a comforter or zip it together with another bag
  • Comfort footbox follows your foot's natural contours to reduce constriction
  • Comfort mummy cut efficiently maximizes warmth without being overly constrictive
  • Internal zippered pocket near shoulder provides storage for your keys, watch, or phone

Cozy and nice.

  • Familiarity: I've used it once or twice and have initial impressions

Bought two of these. Slept great. Overall, a great sleeping bag.

At 5'12" should i but the "regular" or the "long" lamina 0?
I'm a bit afraid of the wight issue, is 3 lb 12 oz/1.64 kg considered decent weight for -5C en rating?
are there any other good options?

Responded on

My friend, it seems that the regular fits to 6'0".
Here is the Lamina 0 in the offical MH website:,default,pd.html
It seems that im on the edge...
What ya think?

Responded on

The bag in a regular size is rated for someone 6' 6", so your 6' height will fit well in the regular. 3lb 12oz is a pretty good weight for a $200 bag. If you want something noticeably lighter, you will need to spend double or triple that.

Responded on

You bring up a good point. There are multiple websites that state that this model (last year's) in a size large is rated for up to 6'6", but it looks as though it could be the interior length. All of the other MH bags are rated for 6' in a regular size. With the interior length being 78", you should still have enough room at their rated max height. I'll put in a note to have Backcountry check their dimensions.

Would not buy this for myself

I used this bag while on a NOLS trip is Patagonia for 3 and a half months and this bag proved to be anything but "0 degrees". Once the weather got below 20 I was cold. This bag also took a lot longer of time to dry after being wet compared to other synthetic bags.
However, this bag is very comfortable, moveable, and packs well.

Just NO.

  • Gender: Male
  • Familiarity: I've put it through the wringer

I used this bag for 8 months in Patagonia and it SUCKS. It was comfortable down to about 20 degrees. Below that and it is miserable. This bag has its place, and if you're aware of its limitations go for it.

Loses loft quickly. Yes it will be warmer than a wet down bag but it will be colder than other synthetic bags.

It is very, very heavy and is not very warm when wet and takes longer than any other bag I've used to dry. Does not pack down small and the zippers get stuck constantly. If you can't afford a better bag this is a great value but if you have the option to spring for a better bag you won't regret it. The only upside is that a friend was giving away a L zip and I had a R zip so it's possible to zip them together for a well you know...

  • Familiarity: I've put it through the wringer

Having been my go to winter bag for countless trips, this bag deserves some praise. It has stood up to the cold Mt. Washington winter weather. Blasted by rain and cold in the pacific northwest. This bag excels in cold and wet conditions where down bags fail. I have had the bag wet several times yet it still kept its warming ability. Its slighter heavier than down, but very versatile and efficient for cold winter weather use. Love the full zip. You crawl inside and you forget what is going on out in the world. It could be a monsoon or a 17 inch dumping and you could careless because you are toasty.

Question. How is this bag so darn cheap?...

Question. How is this bag so darn cheap? I know NOLS used to use Laminas and I've used a 32 ultralamina, which I love. This seems like a deal that's too good to be true...any thoughts?

Responded on

No Mr. Andy Paul, believe it. Its a great price for the bag, I was just going to right my review for it. It was my go to winter bag. Its synthetic so its much cheaper than down to make hence the price. Check my review for performance notes.

Great bag!

  • Gender: Male
  • Familiarity: I've used it several times

This bag is a great buy. Totally worth it. The bag keeps me totally warm even sometimes too warm. I've used the bag on some really cold December nights in NH and its kept me totally warm. The bag stuffs down really small and dries out easily if it gets damp. The zipper tends to get stuck sometimes but if you use it with caution it can work without a problem. Also the lining and shell are very soft and comfortable, very inviting. Overall for the price its a great deal.

Relatively accurate rating, comfortable, luxurious shell

The rating on this bag is fairly accurate, though I'd suggest wearing a layer or two if you're going to push it close to its rating. I've kept mine stored in its large storage sack, and still find it very warm. There is a review below mentioning that they've had some issues with storing it in its large storage sack has caused it to lose its warmth. So be aware of that. Granted, hanging a bag or laying it flat is a great way to store it, but not all of us have that kind of space available.

The shell/lining of this bag is luxurious and quite comfortable. Also, given the fact that this bag is synthetic, it packs down to a decent size and its weight is reasonable.

The Lamina 0 is a great snow camping bag, particularly if conditions are going to be a bit mixed, and consist of some wet snow or even some rain. Also, if you're car camping the larger size and weigh isn't going to be an issue.

If you're backpacking and out in these conditions I'd suggest throwing some more cash at a down bag with a GoreTex shell with a more realistic rating. However, given the price, as long as you factor in the size, weight, and slightly liberal rating of this bag, its a decent choice.

Hooray for short length!

I'm 5'1" and I really like the short length. It's warm and lofty and packs down well. My only complaint is that the zipper gets caught all the time, which is really frustrating. Overall great bag.

at 5"10, short bag a bit too short

I'm 5'10" and the short bag (6')seems to be a tad too short...
fine if you want to feel like a caterpiller ready to escape to butterfly away, but I exchanged for the "regular" (6'6")'s customer service is unparalleled!

Responded on

The short bag is not 6', it's 5'6"

The regular fits to 6' and the long to 6'6". I think you're labeling the bag sizes wrong.

Favorite Sleeping Bag!

I have use a lot of sleeping bags in the past and this is the only one that can keep me warm! When I don't move I don't produce body heat and this bag heats up quick and stays comfortable! I'm able to use this 1 bag all year long and it packs down really small for a 0 degree bag! I love it!

lamina 0

its a real warm bag i did some backpacking in February and it held up fine. the only thing is the drawstring broke around the chin, but no big deal just fed it through and sewed it up. good bag for its price

Pefect for me!

I'm 6'1" tall, 240lbs. The long fit's okay. It's a little long, but I have enough room to fit some clothes at the bottom of the bag. I've slept in a snow trench without a bivy in the high teens with base layers, socks, and light jacket. Kept me nice and warm. The cut is nice and wide for all you with a wide frame, or for those who want a little room to move around. All in all, a great sleeping bag.

not even close to zero degree bag

I'm a warm sleeper and bought this bag for winter mountaineering in washington. It is rarely near zero here - more often temps drop to 10-20 degrees. I am always cold, with a 2" thermarest or a z-rest, in a bivy sack, tent or snow cave. I bought this bag as when I was young and dumb, i used a mountain hardware phantom 32 year round - and wasn't too cold at night with my puffy coat on in the winter. I can't say this is much of an improvement, and is 3lbs heavier! I understand this is a cheap bag, but that should reflect the bulkyness - i have much less respect for mountain hardware after using this bag.

Ok Bag... Just ok.

I'll admit that I have an older model than the one pictured here. I bought mine about 2 years ago. So keep that in mind with this review.

I really want to love this bag. Well, I really do love this bag... that is to say while I'm sitting around the house on chilly nights. It's comfy enough but...

This thing loses it's loft rather quickly even when stored correctly. I took it up Rainier in July when temps never got down below 22F. I wore my softshell pants, baselayer top and fleece while I slept. I was comfortable but not super toasty.

A couple weeks ago, I took it out for some winter camping and the low got down to 13F and I froze my rear off. Couldn't sleep at all and spent the night shivering and tossing/turning even with 2 thick pairs of socks, baselayer top/bottom, softshell pants, and fleece top.

The drawstring at the top works well enough and cinches down.
The zipper gets caught quite often though.
I do love the little pocket at the top. Comes in handy so you don't lose earplugs.
I'm almost 6'1" and I have a long which is roomy enough to put boot liners in the bottom to dry out during the night.
It collapses down decently enough for a synthetic bag and isn't too heavy for the price.

Overall, I wouldn't buy this again. I'll be upgrading to a 800 down bag next anyway. Maybe I sleep cold but this one makes me want to get a -20F just in case.

Try wearing less layers. I know it sounds weird, but the principal here is that you are kept warm during the night by the small layer of air trapped between you and your bag. Your body heat is the primary mechanism that warms that air. Your bags main function is trap your body heat? The insulation of the bag itself also plays a role in this process but your body is what generates heat. Simply put, if you wear too many cloths this layer of air is compromised and your bag never warms up and you are left to rely solely on the synthetic insulation of your jacket to keep you warm

I have had similiar experiences and have spent +200 nights in this bag. Even packing dead air spaces still is not warm. Luckily have a new bag now...

This bag is bad ass! It's light (for the price, and temp rating) it's comfy and it squishes down pretty good for a winter bag. Definitely worth it if you can get it on sale. Mountain Hardwear makes good stuff.
