Super light and super warm, high quality material. Wish the straps would be better resolved
I have put this quilt through it's paces over the past year in the Colorado Rockies and I am astounded by the Alsek's performance! I have used it on trips with overnight lows ranging from about 40F (forecast) to 0F (measured). The weight and volume savings with this quilt while maintaining comfort makes it worth every penny.
The good: The versatility of this quilt means it replaces three sleeping bags for me, a rarely used down 45F Sierra Designs (packed weight 616g/21.7oz), a synthetic 15F Mountain Hardware Ultralamina Long (packed weight 1413g/49.8oz), and a down 0F REI Radiant (packed weight 1823g/64.3oz). The packed weight of my 6' Alsek 900fp Hyperdry (which includes the pad attachment cords and stuffsack) is 666g/23.5oz. This a quite noticeable 26.3oz and 40.8oz weight savings over my (previously) most used bags, in addition to a considerable packed volume savings. For me, the edge of the envelope with this quilt is 0F. I had one comfortable, cozy night on packed snow in December near Tennessee Pass (on the continental divide) at about 10,000 ft and a low of 0F (measured by a Kestrel Drop about 2' above me inside the tent) and a second night slightly chilly at the same temp. My sleep system on the two 0F nights consisted of: ~0.5" thick closed cell foam pad, NeoAir XTherm mat, wool socks, REI down booties, Minus33 brand Merino 706 wool bottoms, GooseFeet down pants (4.5oz 900fp fill), Smartwool Merino 250 top, Arc'teryx Cerium hoodie, GooseFeet down hood, and my Alsek. I attribute the second night's chilly feet to neglecting to scarf a candy bar just before bed, as is my typical practice. I have been very impressed that there are essentially no drafts or cold spots when the pad attachment system is used, even in temperatures considerably colder than the recommended limits. This quilt has kept me warm down to 0F. ZERO DEGREES...fahrenheit! It's just as warm as my previous mummy bag that weighed over 2.5 POUNDS more and was three times the packed volume!
The bad (or more accurately the minor gripe): Using the pad attachment system is a really good idea at temps below freezing. Attaching, unattaching, and adjusting the pad attachment system and neck draft collar is a bit of a pain, particularly from inside the quilt with everything snugged up. One must find and unsnap the neck draft collar behind the neck with one hand (since there isn't room inside to raise both elbows and reach behind the neck) to sneak an arm out so both hands can be used to pop one of the top pad attachment tabs off the attachment cord in order to get out for the inevitable late night whiz. I have not been successful more than a couple times at using one hand to attach or release the attachment tabs yet. And I still have trouble sometimes getting the cord into the tightest lock slot even with two hands. I worry about snapping the tab at colder temps. Although the colder temps may significantly contribute to the difficulty in bending the tabs.
Conclusion: While setting up and adjusting the attachment system takes a little getting used to, it is a minor gripe and will likely get easier with continued use. Fussing with the attachment system is weeellllll worth the savings in weight and volume over mummy bags. It is even a huge cost savings vs the three sleeping bags it replaces.
In hindsight, I wish I would have purchased the Flexquilt in a Regular Wide and maybe even dropped down to the 15F version. At a weight cost of less than 6 ounces, it would have covered really all of my sleeping system needs for all 4 seasons by allowing easier foot ventilation during warmer temperatures (lows rarely get above 50F where I typically backpack) and providing a bigger cozy margin on even the coldest of nights in the Rockies. And the wide version would allow a little more room for me, a mostly side sleeper, to wiggle and adjust the pad attachment system, particularly with fluffy layers underneath the quilt and a small pillow between my knees.
This quilt has quickly become one of my most cherished pieces of UL gear. Absolutely worth every penny! I have pushed it well beyond the intended limits of this gear and been nothing short of awestruck by its performance. Outstanding job, Katabatic Gear!
I used my Alsek top quilt this week on a backpacking trip to Big South Fork in Tennessee. After talking to a company representative about my needs I decided to get the 22° quilt. I'm so glad I did. The overnight temperature was in the high 20's and I was warm and comfortable. I'm a side sleeper who also sleeps cold. I was able to roll over and stay warm throughout the night.
Was nervous about purchasing my first quilt and thought it was a lot of money - especially because of the risk of success. I sleep very cold but do not tend to camp out much under 40 but sometimes hit as low as 30. After talking to customer service, I settled on the Alsek 22 and, at 5’ 6” and a shoulder circumference of 50”, took their suggestions and ordered a Reg Wide. Took out on our trip to Florida, when nighttime temps dropped into the low 30s, and slept unbelievably comfortably. It was so warm inside, I only fastened the clips on one side most nights. No more getting tangled in sleeping bags - awesome - and only 1.5lbs. I could probably have got away with the shorter style but the regular left plenty of room in the foot box for drying socks and keeping clothing warm. Another unseen bonus was the dryness of the bag. Although it got damp nightly from my tiny single wall tent, the dampness never penetrated the bag even when we had to pack up in a hurry not allowing time to air. I have never been so warm and comfortable sleeping outside - and I’m 54 lol. I expect this bag will enable me to tolerate even lower temperatures if necessary and the fastening system was quick and easy to learn.
I have used the Alsek on several hikes now, including Australian alpine (out of Thredbo) and much warmer Wolgan Valley. The Alsek has been outstanding; the quilt is versatile and the product quality is sensational. Highly recommended!
