EN-tested Mountain Hardwear Lamina 35°F sleeping bag uses an exclusive insulation designed to provide high loft, durability, softness and compressibility. It's ideal for damp, cold weather.

  • European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags
  • Lightweight Thermic Micro™ insulation is manufactured to produce a consistent, dense sheet of insulation that eliminates cold spots
  • Made from a combination of hollow and solid staple fibers, the fill has excellent loft retention while also being durable, soft and compressible
  • Slightly wide cut gives you extra room to move inside the bag; Comfort mummy cut efficiently maximizes warmth without constriction
  • Welding stabilizes the fill without sewing through the bag, eliminating moisture penetration points and maximizing loft
  • Insulation is laid in a wave shape, enhancing loft and increasing thermal efficiency; offset welds increase stability and loft
  • Insulated draft tube extends to bottom of bag to eliminate cold spots
  • Face gasket and ergonomic draft collar seal out cold air
  • Full-length, 2-way zipper with locking slider is backed by wide, antisnag binding tape
  • Insulated zipper gusset seals in warmth at base of zipper
  • Comfort footbox is shaped to allow feet to rest naturally; shape preserves loft and allows insulation to drape close to feet for more warmth
  • Interior zippered pocket at shoulder is great for stowing small necessities such as your watch or lip balm, alleviating middle-of-the-night fumbling
  • Comes with nylon compression stuff sack and mesh storage bag

    Comments about Mountain Hardwear Lamina +35 Sleeping Bag:

    I read a lot of reviews for bags in the 25 to 35 degree range before I settled on this one. This bag packs down very small and is on par size wise, with similar down bags.

    I used this bag recently on a 30 degree overnight at the Oregon coast in a Hennessy hammock. I stayed warm and toasty all night even though I collected a little dew in the early morning. The bag dried out very quickly.

    My only complaint was purchaser error. I bought a regular when I needed a large. I'm 6'1" and once the hood is drawn down the bag was too small for me. Thank you REI return policy. It's hard to find a bag that is this good for such a fair price. Get them while they last.

    Comments about Mountain Hardwear Lamina +35 Sleeping Bag:

    I bought this because I was looking for a lightweight, compact 3 season bag. I also considered the REI Lumen 40+ but purchased the Mtn Hardware bag because it was on sale and it offered a lower comfort rating.

    I have camped with it twice and I like how it packs down into a small stuff sack that fits well inside my backpack. I do not find it difficult to stuff into the small sack as some reviewers have said...you just have to pay attention and stuff it to the bottom each time and then it will fit.

    I am a medium size guy with average build, it I found it to be roomy enough for me even when sleeping on my side.

    Some reviewers have commented that the temperature rating is not accurate. I camped with it in in late October in the NC mountains when the low temp overnight dipped to 32 degrees. I had a short sleeve shirt on as well as long john bottoms, socks, and a polypro cap. I was okay temperature- wise, but I would not suggest using this bag in temperatures any lower than this. I do not plan to do any winter camping, but if I did I would get a bag with a lower comfort rating.

    I agree with the other reviewer comments about the zipper snagging. In my experience, most zipper snags occur along the thick nylon tape that runs the length of the zipper rather than the fabric of the bag itself. It seems that Mtn Hardware could easily correct this with a wider band of nylon tape along the zipper. It is a bit of an annoyance but it does not detract from my overall satisfaction with the product.

    Comments about Mountain Hardwear Lamina +35 Sleeping Bag:

    First the good. This bag packs very small (when the compression pack is used) for the price point. It's pretty light as well. So it's a great backpacking bag.

    Now the bad. I used this sleeping bag twice in weather where the temperature at night was in the mid 30's. I was freezing, even with multiple layers on. I was sleeping atop a Big Agnes insulated air pad, so I wasn't directly on the cold ground. I had to boil some water, pour it in my nalgene bottle, and put it between my legs to keep warm. Additionally, the zipper on this thing snags CONSTANTLY! Very irritating.

    I ended up taking the bag back, and now I have a Kelty Cosmic down +20 bag. While it is a bit bulkier, it's much warmer and the zipper doesn't snag at all.

    Comments about Mountain Hardwear Lamina +35 Sleeping Bag:

    I am planning a five month trip to India and Spain. I only want to carry a backpack with all my stuff in it, therefore I want very light weight items. The Mountain Hardwear Lamina +35 Short looked like a good bag online. I opened the box that it came in and didn't pay too much attention to it. As more items were arriving in the mail for my trip I remembered my sleeping bag. I set it on my stairway and thought I'd try it out for the night. When going upstairs to go to bed I picked up the sleeping bag and was amazed at how light it was, thinking "wow, this will be easy to carry along with me, so light." Well....when I got to my bed, opened the sleeping bag and climbed into it I was amazed at how small it is. I am 5'4", about 140lbs and this bag was way too small. There is absolutely no room for my feet, no room for me to move around at all in the bag. I suppose it would be good for my seven year old granddaughter but not for me.
    Although I want the minimal weight I would like a bit more comfort that sleeping with a sheet around me. The bag doesn't have any cushion in it at all.
    I am going to send it back and look for something more roomy and with a bit more cushion yet light weight.
    That was the one thing I liked about the bag, very light weight.

    Functions fantastically. Only reason for 4 stars is the lack of color selection. I camp with a handful of people, so color-coordinating helps prevent gear mix-up.

    Comments about Mountain Hardwear Lamina +35 Sleeping Bag:

    I would echo several of the comments from others. The zipper does indeed snag way too easily. I am bit on the tall and skinny side (6'2" 165 lbs.) and found that there was too much room at the shoulders in the tall bag. The bag does pack down very well and provides surprising warmth given the weight. Generally content with the bag but perhaps could have found something more ideal with more shopping around.

      Comments about Mountain Hardwear Lamina +35 Sleeping Bag:

      First, I'm 5'8" and the bag fits me nicely. However, I'm also very fit, lean with only 8% body fat so I tend to sleep cold. This bag is not for me, in part because it's warmth level does not make it a 3 season bag for me. Lean hikers beware and be prepared to wear extra clothing, maybe a lot, when using it in the stated low range. I will not give it more than 2 stars because of the poor ZIPPER design. It is very poorly designed and snags the little flanges that stick out the whole length of the zipper. Why were these left sticking out? Considerable care must be taken when zipping. It will also snag the bag material but that is easy to undo; the flanges take considerable effort to fix. It is so annoying that I have had enough of it and I am returning the bag to REI. REI bags and others don't have this free material hanging out along the zipper to snag, by the way.

        Comments about Mountain Hardwear Lamina +35 Sleeping Bag:

        Bought this to replace a 20 deg NF Cats Meow I've used for the last 25+ yrs. It's 1/2 the weight, just as warm, and 1/3 the size (or smaller). Wanted synthetic and am just amazed that it packs smaller than my daughter's down (albeit 20 deg) bag. After just 1 night here's my take:

        Warmth: at 45 degs was warm enough w/ bare skin, mostly but not completely zipped up. Will want a base layer at too much colder than that--but wanting a mostly summer bag, about what I expected. With a silk liner and base layer, I'll sure I'll be good to sub-freezing. Had it mostly unzipped when we crawled in at about 55-60 deg.

        Zipper: small snag once, but was easy enough to clear--and I did a fair amount of adjusting during the night, and got up once. So much better than my old bag, but can't compare to other new ones.

        Size: I'm 6'0 210 and got a long. Regular was a tad too short when I tried it in the store. Long is plenty good. Just a bit snug in the shoulders, but about what I'm used to in any mummy bag.

        Comes with a nice compression sack, that's barely big enough for the long--gotta get your weight on top of it to get it in. Guessing it's sized for reg. or short bags. Not perfect, but fine.

        Fabric is comfy. No noticable cold spots. Like the full length zipper and ablility to ventilate the feet. Will open up and use as a blanket in warmer weather.

        So it's light, small, and rated right. The only issue I have is that I now need to get a smaller pack! (upgraded the sleeping pad too)

        Comments about Mountain Hardwear Lamina +35 Sleeping Bag:

        I went back and forth between this and the REI 20 deg down bag. I was worried about being too warm in the REI - turned out I was not as warm as I would have liked in August in the San Juans (a better pad would have helped - that is on this year's list!). I went and bought the REI later anyway - guess my son gets this one. Other problem is that I am a biggish person (6'2", 220) and this is a bit too snug - that probably contributes to the biggest issue i had - the zipper snagging was seriously frustrating. I found it almost impossible to avoid. The REI bag comes in a very roomy large size and i am much happier with it.
