Mountain Hardwear Lamina 32°

A warm, compact, and lightweight 2- to 3-season sleeping bag at a reasonable price.

I have owned the old model and the new model of the this sleeping bag. The new model is a vast improvement over the old model. I've used this bag for desert camping in West Texas, mountain camping in Patagonia, and everything in between.

Warmth: This bag is warm for temperatures 35°F and above inside of a properly protected ventilated tent. At temperatures below 35°F it starts to feel a bit cool. The bag has excellent coverage with no cold spots or drafts.

I've used this bag in temperatures of 40°F sleeping in a hammock and felt adequately warm even with a draft flowing below me. For added warmth down to 25°F I often pack a sleeping bag liner, light synthetic top, and bottom and wool socks. For temperatures below 20° I'll sleep with a down puffy jacket.

Fit/Comfort: I have an average build — 6 feet tall and 175 lbs. The bag fits me comfortably. There is enough room to move around, but not so much room to create cold spots. The old model did not have enough head room, but the new model has the appropriate amount of space. I often use this bag with a Nemo air mattress and this combination is very comfortable. The material is soft to the touch.

Entry and Exit: Access to the bag is good. And probably more important, exiting this bag is easy. The old model had a baffle along the zipper that would snag making exits a difficult task. The new model has a protective fabric that runs the length of the zipper to prevent snags. I've found the bag easy to open and close from both inside and outside the bag.

Moisture: I believe that the light nylon shell has some water repellent treatment. The Thermal Q interior insulation is also water repellent. I've had the footbox get wet due to contact with the edge of my tent. I don't think the water penetrated to my skin. The material did dry quickly. Luckily, I have not submerged the bag in water. 

Packability: I bought this bag for the packability and durability. I used this bag for a yearlong motorcycle trip riding from Texas to Tierra del Fuego in Patagonia. I needed a compact yet warm bag and this one worked out nicely for me. With a compression sack, the bag can pack down to the size of a football.

Loft: The bag has decent loft. The good news is that the bag has maintained its loft after long lengths of time compressed and many years of use.

Ease of Use: The bag works good. The zipper works consistently. The cinch strap around the hood works good. The old model was problematic, but the new design works as advertised.

Features: I do not think that this bag offers any fancy features over other bags on the market. That is one of the reasons why I now like this bag. It is based on a tried and true simple design that works.

Construction and Durability: The seams, stitching, zipper and pulls all function as designed. The fabric material is soft to the touch yet durable. My bag is a dark green color, which does not show dirt easily.

Conditions: I have used this bag in a variety of temperatures and barometric conditions. I've used this bag in West Texas desert, Ozark mountains, Costa Rica coastal camping, Amazon rain forest, and in Patagonia where you might have four seasons in one day. The bag is flexible for all a variety of situations. 

I would like to supplement this bag is with a 20°F down bag or quilt for 3- to 4-season use.
