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°F / 1°C Sleeping Bag is rated 4.6 out of 5 by 24.
Rated 2 out of 5 by from So, so, cold.... I bought this bag at REI late last year. I knew it wouldn't be a 4 season bag, but I was looking for something much lighter than my down EMS bag. I shopped around a ton and fell in love with the weight and design of this bag, at least in theory. I was looking for something that could be a 3 season bag...but this, sadly may not be the best bag for everyone if any of your 3 seasons run the risk of getting below 40 degrees at any point. I took the bag out this last weekend to do 2 days near, then on the Appalachian Trail in PA. My first night out, I set the bag up on my Thermarest and inside an MSR one person tent. Typical set-up...just with a new bag. When I got around to crawling into this super lightweight bag, I was skeptical it was going to keep me warm, and unfortunately, I was right! I started out in underwear, long sleeve thermal tee, and a beanie. I tried to get to sleep but could warm up. So I threw on a Buff to keep my neck warmer, and some clean dry wool socks. Tried again. Couldn't sleep and started experiencing some real discomfort. I dozed off for a bit, but woke due to the pain from cold in my feet. I got out of the bag, put on clothes, threw on the rainfly, to cut down on the little wind there was on this crystal clear night. Tried again....was still freezing. I finally broke down and pulled my pants on, along with light gloves and my nano puff jacket. I took my shell jacket, zipped it up and slid it over the foot of my bag as another layer. This all let me finally get to sleep but I woke with totally numb toes (spooked me in fact). I opened the tent and grabbed my water bottle. It hadn't frozen overnight, so it wasn't that cold. I turned on my phone to check the overnight temp. It hadn't gotten below 37 degrees, but the wind I'm sure added some chill. This bag is cool looking and crazy lightweight. A winner for Summer camping where I anticipate warm temps overnight, but I had to bail after one night out on the trip I described above because I didn't want to risk the temperatures actually getting worse.

Rated 5 out of 5 by from Great sleeping bag but a little long This bag is super comfortable and easy to use. With the addition of a liner I was able to stay warm at below freezing temps at 7,200 ft. I'm 5'6" and my only complaint is that the bag is a little long for me.

Rated 2 out of 5 by from Lightweight, but not for the cold; Love packability Got this for a 110 mile section of the AT in November. It did rain 3 days, but what gets me is this bag I was so cold. I normally sleep naked in my bags and I slept with 3 layers of clothes and still was cold. 32 is the lowest it dropped down to, and man I was hating myself for not bringing my other bag. I do love how light and packable it is. I will come back after using it in spring time and re rate it.

Rated 5 out of 5 by from So light. This bag is a great 3 season bag!!! Pros So light, I’m not sure it weighs anything. Warm I slept in it at 20 degrees F and it was ok, the bag is rated to 32 degrees F and is perfect at that temperature. Wicks moisture and dries itself out while you sleep. Useing this summer In all types of conditions including a week in the rain. Cons Zipper is about 2 in shorter than I would like it to be, makes it a bit inconvenient to get in and out. It is probably that way for warmth. Most definitely not a deal breaker

Rated 5 out of 5 by from I'm in love with this bag! I've had my hyperlamina for two seasons now, and it's fantastic. Definitely the best lightweight synthetic bag on the market for the price, quite possibly the best regardless of price. We dipped below zero on a trip a couple of weeks ago and I was a little chilly that first night, but with a liner I was just fine the second. Pretty amazing for a 1C bag! This bag has pretty much changed my life. It holds up in the damp west coast weather and is light enough that hiking with a disability is made about a thousand times easier.

Rated 4 out of 5 by from Very Light! Overall, great bag, packs down to nothing, very light, very soft feel to it, quality feel to it. For a guy that is 6" 4" it is a real struggle to get into the bag and close the zipper. Once inside, it feels a little more restrictive than the average mummy. The fabric feels great next to the skin. Started to get a bit chilly in it at about 35 degrees.

Rated 5 out of 5 by from Too cold, but fantastic nonetheless Really amazing, compresses and weighs like a down bag, but gives the peace of mind that only a water resistant bag can. I've slept in this semi-wet from a heavy fog and it performed admirably. I feel like the rating is a bit aggressive, so put it firmly in the summer category, I plan on adding an overbag for an upcoming trip. (This review was collected as part of a promotion.)

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 Excellent summer bag The bag is very compressible and lightweight, I was looking to downsize from my 4season bag. The half zipper in the center allows the bag to function similar to a quilt which is perfect for summer.

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.
