    Carry the torch.

    Mountain Hardwear's Lamina Z Torch Sleeping Bag is a protective synthetic bag for the alpine, and it's surprisingly light and compressible for backpackers. Its unique Lamina construction welds the water-resistant shell to Thermal.Q insulation for better protection against moisture. Zoned insulation places more warmth where you want it, and less where you don't need it. Lamina collection bags are lighter and more compressible than other bags on the market with similar temperature ratings.

    Mountain Hardwear cut the Lamina Z Torch into a slightly wider mummy shape to better accommodate alpine puffies. Despite its wider fit, the Torch has a snug, tailored hood with a face gasket to protect your head from harsh winds. It has an ergonomic draft collar down the full-length zipper, and the footbox is bigger for more comfort.

    Extremely Compressable

    • Familiarity: I've used it several times

    Excellent sleeping bag and for being a 5 degree bag it is still fairly light and compressable. This past week, I used the bag for the first time; I hiked 45 miles up the NW coast in rainy and cold 30-40 degree weather. I was extremely glad I had this bag. Although it is a little bigger, it is still under 4 pounds and likely only about a pound heavier than a lot of 20 degree down bags, if that. At first a 5 degree sleeping bag seemed overkill for the forecasted weather ranging between 29-40 degrees, but I didn't have to worry about hauling too many extra dry layers to sleep in. At one point, climbing over a moss covered boulder field at low tide, I slipped into the water landing on my pack. Although I got out quickly, I was definitely glad I had a synthetic bag in case it did get wet.

    I do most of my outdoor adventures in Western Washington and so there is huge potential to get wet in the rain, especially in the winter. After having used a down bag out here, I was happy to swap it out for a synthetic. I have an 85 liter pack and it fit nicely in the bag compartment. What pushed me over the top was finding this review ( The compression sack that the bag comes with isn't bad, but I likely will swap it out for the suggested compression sack in this vid. Although not a great summer bag, I will just get another for spring and summer.....

    Great budget bag

    • Familiarity: I've used it several times

    I used this bag while backpacking through the cirque of towers in Wyoming. This bag worked wonders as we fought thunderstorms, and on the last day woke up to some September snow. Glad i had this synthetic insulated bag as it dried really fast. I usually feel a little cramped in a mummy bag but i felt i had plenty of room. The only issue i had was it doesn't compress as small as i would like. It took up a lot of room in my pack. Besides that this bag will be keeping me warm all winter long touring around the wasatch.

    Couch tested

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

    Honestly, the only time I have had occasion to use the sleeping bag since I received it has been on the couch to test it out. I'll update this review once I get it outside in a few weeks.

    Initial impressions: I am always cold. Literally, every day of my life I'm freezing at one time or another. As soon as I crawled into this bag I was toasty warm. I've been outdoors on a few cold nights before and I'm convinced this will be the first bag to actually keep me warm. Without being fully cinched you can sleep in just about any position you want with comfort. I tend to toss and turn so that matters for me.

    Synthetic is important to me because I try to be animal friendly as much as possible in my outdoor gear. Down is just not an option, so that means I have suffered with pack size for a long time. This is the most packable synthetic bag I have owned so far. The weight is pretty par for the course in synthetic (especially with the extra room in the comfort mummy style) but trends on the lighter side.

    More to come as the real testing begins.

    Works for Stomach/Side sleepers Too!!

    • Familiarity: I've used it several times

    I was super stoked to try out this bag in some gnarly conditions. So we loaded up the gear and headed to the Colorado Rockies on a ski trip. We stayed several nights at 11,000 + ft with several feet of snow on the ground.

    Position Comfort: I was super happy with the comfort of this bag. My biggest problem with mummy bags in the past was not being able to sleep on my stomach or side and still be warm. Because the Lamina Z Torch is pretty wide at the top though, it allowed me to put my arms up under my head with my elbows out. You can still really only breathe out one side if it's cinched up pretty tight so choose the left/right zip according to which way you prefer to have your head face. It also works for back sleeping of course, and if i really really really had to just stay warm, I'd just lay on my back with just my mouth and nose sticking out. But that wasn't necessary on this trip. The bottom half of the bag is pretty slim, so if you like to spread your legs when you sleep, look for something else. But this slim fit helps you stay warm, all the way down to your feet.

    Temperature: It was in the low teens most nights while we were up in the mountains. I was never cold at night though. I was wearing several layers of clothing though, thermals + fleece + puffy jacket + beanie, AND I had a really good thermarest pad underneath me. That being said, I think I still would have been warm with less clothing, I just didn't want to take any chances. I did try one time, cinching up the draft collar around my shoulders just to see how warm I could make the bag. I started sweating almost immediately. That thing really traps the heat! On our way back from Colorado we stopped by Moab, where the temperature at night was around 45 degrees. I unzipped the top half of the bag and had it over me like a blanket with my stomach, arms, and head just on my air mat. It breathed very well, and by using the zipper at the bottom of my bag, I was able to avoid that sticky, clammy feeling you often get with synthetic bags.

    Other features: This bag has some other features that are pretty dope. For one thing, you can stuff it down to a similar size as a down bag. With my cinch bag all the way compressed, I got mine down to about the size of a large Rugby ball. Don't ask why that particular object came to mind, it just did. It fit easily inside of my sleeping bag compartment on my Osprey Aether pack. Another feature that I like is the tiny little zip pocket up near the top of the bag. It's perfect to store ear plugs, chapstick, or other essentials that you don't want to have to scrounge around and look for in the middle of a freezing night. Another plus is that the bag comes with two stuff sacks, one that is very compressible, and another meshy one to store the bag in long-term. I also noticed that the material on the bag dries very quickly. I wet the bed almost every night and..... Just kidding, but I did spill quite a bit of water on the bag one night and I was kind of worried it wouldn't dry because it was already so cold. Within 5 minutes though, the water was gone, and the bag was completely dry.

    Complaints: Only one complaint- the zipper catches on the material almost every time you try to zip it up or down. Annoying but manageable. I think it's mostly just because they put a lot of material right by the zipper so drafts don't get in. It's not that difficult to get unstuck so I think it's worth it.

    Bottom Line: This is by far the most comfortable, functional, and sexiest sleeping bag I have ever used, and highly recommend it. And if you're a stomach or side sleeper, have no fear because there is plenty of room up top! Well done Mountain Hardwear, well done!

    Works for Stomach/Side sleepers Too!!

    More room in the shoulders

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

    I picked this bag up to have a synthetic for river trips. I used it on the Green River for a 9 day trip. I'm glad I got the 5 degree temp rating because it was pretty cold at night. I found this bag to be nice and roomy as well as warm. I like to roll around a bit while sleeping and the shoulders are more roomy than other mummy style bags I own. I also like how compressible the bag is for synthetic insulation. The welded seems keep condensation from getting to the insulation too. With how small this 5 degree stuffs down, I will be taking it on backpacking trips and it is sub 4 pounds. I have not carried a synthetic into the backcountry in a number of years but I will put this one in my pack. Not nearly as bulky as my old synthetic bag of the same temp rating.
