Summary

Thermally mapped insulation and half-length center zip maximize efficiency. Engineered to be one of the lightest and warmest synthetic bags on the market. Lamina™ construction welds the Thermal.Q® insulation to the shell and lining, eliminating the cold spots caused by traditional stitching. By mapping different insulation weights throughout the top of the bag we are able to concentrate warmth where you need it most – around your core and feet. Thermal efficiency is optimized by a performance mummy-cut, face gasket and single center half zip.

Reviews

HyperLamina™ Flame 20°F / -6°C Sleeping Bag is rated 4.5 out of 5 by 11.
Rated 3 out of 5 by from Heavier than spec This bag appears well designed. I prefer a center zipper, the foot box is great, and the laminated baffle tech is awesome. I got the Long and like most long bags it is wide (true to spec, 66in shoulder cirumference). I anticipated this and for my intended use (with belay jacket and puffy pants in cold temps) it was good, but if you're a tall skinny guy looking to sleep in your underwear you'll find it roomy. So my main issue is this: mine was 15% over spec weight. My Long (spec 42oz) was about 48oz on my scale. My scale isn't that far off (it weighs a 200g test weight at 190g) and my other gear weighs very close to manufacturer specs. Maybe it doesn't matter to most people, but it does matter to me and MH clearly market this towards alpinists (Good For: Alpine Climbing) who are notorious gram counters. I would have kept it if it were true to spec but 3lbs is getting hard to justify for a 20F bag.

Rated 5 out of 5 by from Great Bag I've used this bag through a wide range of temperatures and it has been good. It looks brand new after a couple years of use. There is one con, if I were to replace it I would get a full-zip bag.

Rated 5 out of 5 by from Great Sleeping Bag This bag is extremely light. It packs down really small and is still very warm.

Rated 5 out of 5 by from Great Bag! I got this bag for spring & fall trips and I just took it out for its first test run on a backpacking trip in the Adirondacks. Early September and we had two nights of temperatures just below freezing! This bag was perfect! I was toasty warm in just base layers, and it packed down very well into a compression sack. Great piece of gear!

Rated 4 out of 5 by from Great bag, But I Couldn't Deal With the Half Length Zipper I tend to overheat in a sleeping bag even when it's freezing out. So when I saw this bag I was really psyched about the ability to unzip down the middle to air out more evenly than you can with a side zipper. Unfortunately when I got in this on the floor of my living room I realized that I would really miss the ability to put a foot out at the bottom to regular my temperature. Often I like to keep the bag snug over my torso but open at the bottom. This is not to say that I wouldn't recommend this bag- it really is a great, warm bag that packs very well (even though it has synthetic fill). If you sleep easy and don't overheat easily this bag would be a great buy!

Rated 4 out of 5 by from HyperLamina I just received this bag and so far I love it. The fit is great (I am 5'10"). The center zip is also excellent and very useful. I will be using this bag for the upcoming summer season on the North Slope of AK. I will update/write a new review after a full summer of use. I only give four stars as I have not used it enough to warrant a five star.

Rated 4 out of 5 by from Casual camper I bought this sleeping bag for my son for a few Spring outings. He likes it a lot--comfortable, soft, functional. His only drawback is that it runs a little snug for him. (However, he did NOT want me to return it. :) For a guy, I would say his build is average--5'11'', 36' waist. Otherwise, I would have rated excellent instead of good. The quality of materials is excellent. Very good value.

Rated 5 out of 5 by from A1 I've used this bag on multiple overnighter kayaking tips, and I feel that it has performed super well in cold wet environments. Even when everything is covered in dew in the morning, I've been warm and dry.

Rated 5 out of 5 by from Innovative bag First , let me say I have only used this bag for one 3-night backpacking trip in the Wallowas in late September, so my experience with this bag is minimal. However, from what I have done with it so far, I really like it. Things I appreciate about this bag: -the center zip ROCKS. It's in such a natural and easy-to-access location. Why aren't more bags built this way? Also appreciate the double-pulls so I can vent my core -the draft collar and double-pulls allow for great customization of the face and retain heat very well -the bag is ultralight for its temp rating, very warm, and very compressible -kept me toasty into the low 30s naked, no liner Cons: -none so far!
