Our Verdict

Product Discontinued
The Ultralamina has been replaced by the Mountain Hardwear Hyperlamina Flame. See below for a side-by-side comparison! Also, see our latest results from our backpacking bag tests

Extended trips in wet climates, big wall climbers, and NOLS and Outward Bound students can't beat the warm-when-wet performance of the Mountain Hardwear Ultralamina. It retains its loft and insulating properties even when you're soaking wet and offers several features that set it apart from the synthetic competition: a small hood opening and full neck baffle to seal in warm air. Unique laminated construction saves weight and increases warmth and weather resistance. Our testers have spent months inside the this bag in Patagonia. There's no other bag we'd rather have when everything else is damp and miserable.

The Mountain Hardwear Ultralamina 15 is our highest rated synthetic sleeping bag. It earns high marks because it's made with high quality materials and constructed in an efficient and innovative way. It is lighter and more comfortable than other synthetic sleeping bags.

For wet trips in warmer weather we prefer the Enlightened Equipment Prodigy because it's 12 ounces lighter and nearly as warm. Check out our full Backpacking Sleeping Bag Review to see how synthetic bags compare to their down counterparts tested. If saving weight is a top priority, consider a down backpacking sleeping bag and if you really need to go light, see the Ultralight Sleeping Bag Review.

The New Version of the Mountain Hardwear Ultralamina 15 vs. The Mountain Hardwear Hyperlamina Flame


Mountain Hardwear has replaced the Ultralamina with the Hyperlamina Flame, which retails for $240. The new center front zipper is the chief difference between the two designs. See below for a side-by-side comparison, with the Hyperlamina shown on the left and the Ultralamina pictured on the right.

Hands-On Review


This high-performance cocoon is filled with Thermal.Q fibers, a quality synthetic insulation, and uses a lightweight ripstop nylon shell fabric. These materials are soft and silky, and the insulation is light and feels more like down than the heavy, suffocating feeling of other synthetic bags.

Performance Comparison



Warmth


The primary factor enabling this bag's high warmth-to-weight ratio is its unique laminated construction. This process uses an adhesive to bind the insulation and shell material. The end-result is a flat, stitch-free seam that's lighter, warmer, and more water-resistant than traditional construction. It has greater water resistance because there are no holes for water to permeate; it's lighter because there are no seams; and its warmer because the insulation isn't pinched at the seams (see illustration below). This construction makes it particularly well suited to unprotected alpine bivis.

Weight


At 43 oz.(size reg.) this bag is comparable in weight to some of the down sleeping bags in our review. Although not super light, it comes with the insurance that if your bag is wet, you will stay warm. A wet down sleeping bag will lose its loft entirely and will not keep you warm at all.

Comfort


The lightweight nature of the insulation in this bag makes it more comfortable than comparable synthetic bags like the North Face Cats Meow. Synthetic insulation is not as light and luxurious as down and can feel a bit smothering.

The Ultralamina has a comfortable hood. There are three good characteristics about the hood area. First, the bag has differentiated pull cords (one round, one flat) so you can tell what you're tightening by feel in the dark, not sight. Secondly, an elasticized draft collar let's you reach outside the bag without loosening the pull-cord. Lastly, like most Mountain Hardwear bags, the hood is compact and only needs to be tightened in temperatures near the bag's limit. These three attributes make the hood area more comfortable than most other sleeping bags.

The draft collar in this bag detracts from the comfort of the bag. The cinching cord for the draft collar is positioned below the collar itself. When tightened, it lessens the circumference of the entire bag. This tightens the fit around the shoulders especially. The draft collar has no closure (velcro or snaps) but the puzzle piece like shape of it fits well around your neck and still keeps warm air in the bag.

The Ultralamina has a slightly relaxed fit, which is comfortable and allows extra space for layering clothing if you are a cold sleeper. The extra space in the bag will also allow you to throw damp clothes in the sleeping bag to try to dry them or just keep them warm overnight.

Packed Size


Synthetic insulation does not compress as much as down. This bag comes with a decent quality compression stuff sack that packs it down to a reasonable size to squeeze in your pack.

Versatility


Warm-when-wet synthetic insulation is hard to beat when you need it. This bag excels in wet conditions. Due to its lightweight construction and soft feel, the Ultralamina is an acceptable bag for general backpacking use if you prefer the security of knowing it will keep you warm if it happens to get stormy. The 15 F temperature rating makes this bag a good choice for three-season use, and it has a slightly relaxed fit, which allows you to add clothing layers if things get too cold.

Best Application


The Ultralamina 15 is built for wet weather. Its best for unprotected alpine bivis or extended trips that span multiple climates. Because of its loft retaining properties, a high quality synthetic sleeping bag like this one is a good choice for outdoor education programs where guides take less experienced groups on extended trips. Beginning backpackers may not have developed the skills or tricks to keep their sleeping bag or themselves dry.

Value


Although synthetic insulated bags are typically marketed as less expensive alternatives to down bags, we've learned by testing sleeping bags of all types and styles that down bags are more versatile and a better long term investment than even the best synthetic bags. The Marmot Sawtooth 15 is a warm bag that is comparably priced, weighs the same, and is filled with water resistant down. We believe the only reason to get a synthetic bag is for maintained performance when the insulation is wet.

That being said, for a high performance synthetic sleeping bag, the Mountain Hardwear Ultralamina is a great value for a reasonable price.

Conclusion


Overall, we consider the Ultralamina 15 to be one of the best synthetic sleeping bags available. It is comfortable, warm, and light for its category.

This review is written after using the Mountain Hardwear Ultralamina (Extra long) in Patagonia for 60+ consecutive days sleeping in a tent/hammock/under the stars.

Pros:
Very warm
Roomy enough to fit clothing that needs to be dried
Well fitting mummy hood
Tough fabric that repels water well

Even when the outside got wet from the tent or someone coming into the tent while wet the inside never even got damp.

Cons:

Broke 2 of the bungy cords (did not rip any of the main bag when they broke)

I used this sleeping bag for more than two months straight in Patagonia for a variety of activities. Sea Kayaking, hiking, rock climbing (in a base camp), and general chill camping for a couple days.



Bottom Line: Yes, I would recommend this product to a friend.

Hey Davor,

I'd like to clarify/correct an issue noted on the zippers. It's not the zipper, but the pull cord on it. I've not had any issues with snags. Frankly speaking, how it comes configured is confounding.

The nylon zipper cord goes through BOTH holes of the zipper from the factory. This is a real problem when you are trying to OPEN the zipper. The thickness of the cord sits against the zipper pull and the zipper itself. This obtuse angle makes opening VERY difficult.

Solution: re-threading the pull cord through a single hole as pictured which allows the zipper handle to pull straight down and makes opening easier. I'm including "before" and "after" photos.

Before:
MH Ultralamina zipper pull original configuration
MH Ultralamina zipper pull original configuration

After:
MH Ultralamina zipper pull modified configuration
MH Ultralamina zipper pull modified configuration

It's a simple matter to avoid this issue by re-threading it. The test run in the back yard (hence the tags were still attached) was excellent: temps dipped into the upper 20's and I was very comfortable.

A very good bag, very warm, soft to the touch ripstop nylon panels, and it cinches up really well. For those of us who like being wrapped up, this is a very solid synthetic bag. Managed to steal it for $179, replacing my old bag. Very happy with it's workmanship - very light for a synthetic bag - and the lifetime guarantee on workmanship. Since I'm very careful with my gear, it should last a very long time.

Agreed on the stuff sack challenge… it's a real test.



Bottom Line: Yes, I would recommend this product to a friend.

Davor · Split,
This bag has felt warm and confortable, with enough room and a nice feeling in contact with body. It has stayed warm and dry in a variety of conditions, even with light rain, and heavy condensation. (but I have not tried it yet anywhere near it's low temperature range)
All of this is very important!
At the same time I felt there are some important flaws:
1) the bag has turned out to be both bigger and heavier than stated on the official page.
2) the zipper looks "hmm…? fragile!", gets stuck a lot on itself, and on the fabric. I wonder how is this going to hold in time.
3) the design of the shoulders collar is quite unconfortable, the whole collar feels to be misplaced, the draw cord ends up lying under the shoulders, where I can feel it a lot. Also the small hood feels too small!
4) to pack the sack in it's bag, is a not so easy everyday task (but it will sure make my fingers and wrists stronger!)

So at the moment… only 3 stars out of 5!



Bottom Line: No, I would not recommend this product to a friend.
