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

Mountain Hardwear Lamina +35 Sleeping Bagis rated4.0out of5by5.
Rated4out of5byfromGreat bag!! Get one...I love the bag. I sleep pretty warm and this bag kept me plenty warm in sub 40 degree weather last weekend. I usually sleep in shorts at most and this bag was great, I never felt cold at all. If you are looking for a good backpacking bag this is it, the stuff sack is crazy small!

Rated5out of5byfromGreat bag for OregonI 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.

Rated4out of5byfromGood Lightweight 3 Season BagI 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 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.

Rated3out of5byfromNot as warm as expectedFirst 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.
