Summary

Highest performance synthetic bag on the market. Thermally mapped insulation and half-length center zip maximize efficiency. Engineered to be the lightest and warmest synthetic bag 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™ Spark 35 (Regular) is rated 4.8 out of 5 by 11.
Rated 5 out of 5 by from Awesome three-season bag! I use this bag for backpacking in the mountains, mainly in Washington, Montana, etc., where the temps can dip down into the 30s in the summer on a cold night. We have encountered some pretty unfortunate weather, even for summer, but this bag has kept me toasty through it all. I am a naturally cold person and any time it dips below 70 degrees I'm dressed for winter, so I was a bit leery of this bag at first. However, it has far exceeded my expectations and being so warm in it in low 40s and high 30s, I would be willing to risk lower temps with it. Excellent bag.

Rated 5 out of 5 by from Solid Synthetic Bag Have only used this bag a few times, but so far I'm loving it! Warmer than I would have thought, and super lightweight. This is my 3 season bag in Montana.

Rated 5 out of 5 by from Packable, comfortable, perfect! Got this as my spring/summer backpacking bag and it is fantastic. Here in the SW we've had a few warmer weekends that have been perfect for this bag - lows in the 35-40deg range. I literally LOL'd when I packed this bag down, dropped it into my empty backpack, and it seemed to free-fall into the cavernous confines like a penny down the well.

Rated 4 out of 5 by from Good to -10F Good to -10F are you mad? Not entirely. I had this in a lean-to at Katahdin this winter and straight air temperatures dropped to a whopping -10F overnight. Midweight thermal bottom and an Arcteryx Atom LT hoody with a thin merino top is all it took for this bag to be taken an extra 45 degrees beyond the recommended range. I wasn't shivering either. The synthetic insulation even stayed dry and lofted with some light blowing snow. I now use this bag all year and have abused it quite a bit. The outer fabric stands up. The hood is great. Theres plenty of room, but fits slightly snugger than some mummy bags, but not at this weight. My only gripe is the cheap zipper system. While it is light, I snag the zipper on the fabric nearly every use. As a result my bag is now taped up in a few places internally. The partial length zipper is also a bit tedious if you're trying to get out of your sleeping bag quickly.

Rated 5 out of 5 by from Surprisingly Warm I do most of my backpacking in the mountains of Montana, where even in the summer it's not uncommon for nighttime temperatures to dip into the 30's. So for me, the HyperLamina Spark 35 is a late spring, summer, and early fall bag. Temperature ratings on bags are a complete crapshoot in my experience, but the 41 F comfort rating on this bag I think is pretty accurate. It compresses down almost as well as a comparable down bag, and it's almost as lightweight as a down bag, meaning you truly do get almost all of the benefits of both worlds, synthetic and down. Highly recommended.

Rated 5 out of 5 by from Amazing! I've used this sleeping bag few times in the Uintas and it kept me warm all night. No more cold spots for me. It really worked! I love how light and small it pack into. Great job MH!

Rated 5 out of 5 by from Solid Fit and Function What did I notice up front? The size the bag compresses to; truly a great hiking bag at its size and weight. The central mid length zipper is different and I thought it would give me grief, but it was the opposite. I had no issues with the design. I found it actually nicer than a full length. I never had to search in the night for its location. The fit is mummy style. If you are a semi-stomach semi-side sleeper who likes to spread their legs around you may be uncomfortable. I am a side stomach or back sleeper and found the design the right balance of room and fit (I am 5'10" @ 155 lbs). The design having varying thickness of insulation to keep the bag light yet warm worked well. I was completely comfortable down to 40 degrees (it did not get any colder on my trip) in just sleeping shorts. I did not experience any snagging of the zipper on the synthetic fabric and the seams did not cause any abrasions on my skin. I would recommend this product to a friend.

Rated 5 out of 5 by from Exactly what I needed I was looking for a lightweight bag for a backpacking trip in the Wind Rivers but I was worried about this bag not being warm enough. After reading reviews, I decided to give this one a shot. I spent 6 nights and was very satisfied. The first night, it was already 40 degrees by 10 o'clock. It probably got to about 35 during the night. I slept in my socks and long underwear and beanie and I slept just fine. The other nights were between 40 and 50 degrees each night. I didn't end up using my long underwear or socks those nights and was warm each night. No issues. I had no issues with the half-zipper. It didn't feel confining or restrictive. I am just short of 6' and ordered the regular size. When I lay flat and stretch out, my feet hit the end. It didn't end up being enough to be a bother but it was close. If I were to order again, I still think I'd order the regular. I weight about 190 lbs and felt like I had enough room to be comfortable, given it is a mummy bag. I mostly slept on my side. The bag packs down nice and small in the supplied stuff sack. I weighed it with a luggage scale after packing it in the stuff sack and it weighed in at almost exactly 2 lbs. I also like the fact that it is a synthetic bag since it will be a bit lower maintenance. All in all, I am pretty happy with the purchase and would definitely recommend it to others.

Rated 5 out of 5 by from Lightweight synthetic bag! Went on a eight day 93 mile thru hike of The Wonderland Trail around Mount Rainier with this bag. I found it to be very comfortable and plenty warm for the conditions I encountered. I am 5'10" and I had enough room to not feel constricted. I used a very thin silk liner, and slept in micro light merino wool thermals. The coldest night was 35 degrees. Some nights I was warm enough to keep the zipper open to vent, on colder nights I was all zipped up with the hood cinched. I feel with wearing more layers combined with use of a liner I could push the cold rating a bit with this bag, but it is what it is. A remarkably warm synthetic bag considering how small and lightweight it is. At this weight and temperature rating, combined with how synthetic bags recover from moisture, I feel this bag beats it's down comparative. I loved the center zipper, found it to be more comfortable than a side zipper, and didn't miss the venting options of a full length side zipper.
