  • 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

  • Comes with nylon compression stuff sack and mesh storage bag

by fromDevil's Advocate I have to be brutally honest on this bag. Mountain Hardwear is generally my go to brand for quality, but this bag did not stand up to any test. I gave it two chances and on both occasions the Lamina failed to keep me warm. On both trips I used this bag temperature was around 40F and at the lowest 25. I found myself on both occasions having to boil water and storing it in a Nalgene for extra warmth to maintain some small bit of comfort. I plan on returning this bag well before my next trip. I used a thermarest sleeping bag for ground insulation and slept in a cotton hoodie and thermal pants and still was cold. To give my self rebuttal argument I may be more inept to getting cold, but I do think this bag should have kept me warmer than it did. Best part of this bag: Stuff sack was great. Storage Sack comes with me on all trips simply to store other items.

by fromOkay... I loved this thing in the store. But what they don't tell you is that it requires a full grown man to stuff this, and even then I have a hard time. I think this would be great, say, for going on a warm outing, but otherwise, go with something else. I do not like this bag, but I will miss the size.

by fromHiccup but annoying I just received the bag yesterday so I have not yet had the opportunity to use the bag. My annoyance is that the stuff sack it too small to get the bag into. I tried multiple times and rolled it in different ways, I even tried stuffing it in without rolling it but it would not fit. I did not buy the sleeping bag for the compression bag but if it comes with the sleeping bag, it should fit.

by fromlet down I thought this bag would be perfect for me, on it's first run out i was happy with how light and compressed it was, but two nights of freezing changed my mind. It was probably in the low fourties high thirties (F) and i was completly warm - except my feet, which just froze. Tried sinching down the hood until i had just my nose sticking out, but still no help. Ended up wrapping a sweatshirt around my feet and slept okay toward the morning of my second night. Anyone re-designing this bag... I would reccomend some extra fill in the foot area.

by fromreturned At first I was excited b/c this bag pack small, light weight, and a nice green color that doesn't stand out too bad. Two nights, both of them right at the temp rating (I'm assuming... cold but still dew on the ground - not frost) and the bag seemed to keep me warm everywhere EXCEPT my feet, which just froze. Ended up wrapping a sweatshirt around my feet the second night and wasn't toasty but at least I could sleep. Also, I am not a really big guy, but my shoulders are pretty wide and I felt constricted in this bag. Still looking for something synthetic, light weight, and will keep me warm down to 30 deg...

by fromIt's the zipper, not the 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.

by fromWOW!!! 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.

by fromGreat bag with a bad habit I have used this bag now on at least 15 different trips all ranging from 2 days to 10 days. I will say that the bag is rather light weight, synthetic (important if you are on a river or in a really damp climate), fits very well and easy on the wallet. My one and only complaint is the zipper. EVERY TIME I USE THIS BAG THE ZIPPER GETS SNAGGED. This isn't over-doing it either. I usually just give up, climb out of it and smack myself around a tent (can't sleep in a shelter because I'll wake everyone fighting with the bag), go do my business, climb back in and leave it where I lost the battle. I'm almost about ready to take it back for another bag but I can't get over not being able to find a bag like this anywhere else for the price. All and all, a great bag but the zipper I think is a major factor. I plan on writing to Mountain Hardwear to see if something can be done about this.
