Award Winning Ultralight Quilts

Really stoked on the design and detail. Only spent one night in it so far camping on the west coast of Canada.

Humidity/moisture wasn’t present so I can’t comment on its performance with dew/condensation just quite yet. Love how lightweight and compact this is, it kept the bugs out and the mesh seemed to stay off my face even without using the tie-out. The top material is really light and looks like it warrants being pretty careful with but that’s the trade off for ultra light weight!

I’ve had “waterproof” bivy sacks before but I always ran into internal condensation problems as they didn’t breathe properly. I plan to pair this with a tarp/shelter when moisture may be an issue so hopefully with that combo the condensation that accumulates in the less breathable ones will be a non issue in this more breathable one.

I ordered the long, wide 22F. I'm 180 pounds and 6'3" and F. The bag is really nicely made and finished, the down is lofty and luxurious. I've used it for 4 nights. I'm using it with a MEC sleeping pad with an R rating of 5. The only night I was cold under it was the night I was forced to set my tent up on gravel in -2C weather, so I was losing a lot of heat through the pad, but also some through the bag. I was only wearing wool long johns and found I could have used another layer of clothing at least. Otherwise, it has been warm, and pleasantly not sweaty or un-breathable feeling like cheaper nylon can be. On nights close to 0 I have thrown my down coat inside of it over my hips, as I've found this is the only area that I get a little cold. I got a zippered footbox and have been using it with the bottom cinched all the way shut. The way it attaches to the sleeping pad has worked well to prevent drafts, and the snap and drawstring at the neck work well with the draft collar as well. None of the hardware gets in the way or is noticeable when sleeping except the drawstring at the neck is in the centre and so theres no choice but to have the excess cord drape over your neck. It is a minor thing. I'll be keeping it and hope to use it as my sole sleeping bag, as I'm a 3 season camper.

I did a LOT of research before I decided on Katabatic. Overall their products seemed better quality and I wanted the extra baffles at the feet and head. I decided on the 6', standard width, 22 degree quilt, I'm petite-ish, 5'7" and figured this would be fine for me, and I was right, its perfect. There is enough width that I can attach it to the cords and have enough room to turn over, and enough length that I can pull it up over my head when its cold. I've taken this out on two backpacking trips so far, each time the temps were freezing (32 or below) at night. I get cold easily and have never been warm at these temps out camping before but I was this time! Shipping was much quicker than stated, it got here well before my trip. By far my best camping purchase! I can't recommend these guys enough!

It fits! Keeps my head warm during those chilly nights. You need this!

Super light and super warm, high quality material. Wish the straps would be better resolved

Arrived very quickly and appears as advertised. There are two stake loops on each end which was a pleasant surprise. Weight on my scale was 7.5oz with stuff sack. I’ll try to update after it’s intended use with Zpacks Hexamid pocket tarp with doors.

I needed the quilt for my pct thru hike and rhe guy's got it to me in time. Super warm and great craftsmanship as usual 😀

Haven't used it yet but looks like quality...first trip is end of May 2021. Tell you much more then!

This is my second Katabatic Flex. I've owned a 15 for years and love it. Wanted a 30 for the warmer times of the year. The craftmanship is flawless, the strap system works absolutely great and the ability to open it all the way when you want is awesome. I am a Katabatic Gear customer for life. Also, i emailed them and explained that i was in a bit of a rush and I had my quilt super fast. Keep up the great work. THANKS!!

This is my 3rd quilt from Katabatic. My last Palisades was blown off a 500 ft cliff by a helicopter during a rescue operation in a major snowstorm in AZ. I recently recovered that one along with other gear after 2 months in snow and rain in a canyon, and with some down wash it seems to be recovering nicely.

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!

European reseller was out of stock, so I paid a bit more to get it direct from the states. Really pleased with it so far. I've only been in the garden so far due to Covid lockdown, but it was -1 degrees Celsius and I was toasty in a bivvy bag.
The quilt is so light but exceptionally well made and built to last.
The only minor cosmetic issue is the huge, white safety label sewn to the outside of the quilt. You can cut it off, but you can still see a bit of white material left behind (I didn't risk cutting too close to the stitching). I suppose it could irritate your skin if it were sewn on the inside though.
Overall I'm super happy with it and it compliments my Alpkit Cloudcover summer quilt nicely.

I recently took my new Flex 30 quilt with me to the Olympic National Park for a late winter two-night backpacking trip. The first night, it ended up being much colder than I'd anticipated, well below freezing. When I woke up, my tent was literally covered in a crackling sheet of ice. While perhaps it would have been better to have a Flex 20, I was able to get by with thermal underwear, a nice liner, and an extra blanket. The thermal protection was probably much like any other 30F bag, and I loved the soft fabric, super comfy, but those things seem fairly standard in high-end quilts. The connection system is what really shined here. Before my hike, I taped the connector cords to the back of my sleeping pad and when it came time to dive in, I attached the little tabs on the underside of the quilt. This system is really the reason I bought this quilt and it worked great. I found, however, that if you don't clip it in all the way so that it locks tight, then the tab will come off the cord as you sleep, especially if you're a side sleeper like me and constantly turn from one side to the other. Having those tabs come off the cords really shows how valuable they were--the cold air seeped in almost immediately, leaving cold spots on my back. The next night, I made sure to pull them all the way tight on the cord and they stayed there just fine all night. I am a big guy with very broad shoulders and the quilt felt way more spacious and comfortable than any mummy sack. Really great.

I was hesitant to buy another top quilt but I took a chance on it and wow was I surprised very high quality. Thank you Katabatic

Quality is awesome. The 30 degree quilt is light as a feather but ultra warm. When my back hurts, I fold it up and place it there. In a minute it has heated up to the perfect temperature to act as a heating pad ( no electricity). Fantastic!
