I used this quilt for the entirety of my northbound pacific crest trail thru hike from may 16th to august 2nd. I had no complaints on my 850 fill alsek. Paired with a full length length thermarest neoair, and one pad strap, the only times I was cold was when I was low on food. Most of the time I did not use the strap, as even without any straps I did not have air gaps between the quilt and my pad. I carried only a very light mid layer and wind jacket, and was confident in the safety net this quilt and my single wall trecking pole shelter offered in the event of something going wrong. I appreciated the heavier ripstop on this compared to other quilt companies, as I am not gentle on gear, and have had issues with past quilts.
I never found myself never having to think about anything with the bag. Sleep with it, stuff it in my pack with a plastic shopping bag if it's wet, and repeat, day after day with no issues. The bag just works. The stitching pattern on the quilt solves the issue with the EE quilt's snail stitching pattern, where the down can bunch up. I never had to reshuffle the down in the quilt and I had no cold spots.
I plan on putting many more miles and long trails on my legs and am confident this bag will be there to hang.
After decades of struggling to roll over in a mummy bag, I finally took the plunge and went with a quilt. There is quite a bit of competition out there, but I went with the Katabatic Alsec 22 for it's overall weight, 950fp Hyperdry Down, collar and pad attachment mechanism. As we headed north hike a week-long section of the Superior Hiking Trail, the forecast showed the overnight temps dropping into the 20s, which made me wish that I had added a 1 oz overfill. I needn't have worried. After struggling to attach the quilt to my pad (more on this later), and learning how to tighten the down collar and slide down in the bag, I was toasty warm all night. This despite being in a tarp that didn't keep the high wind gusts entirely off the bag, and measured temps of 23 degrees the first two mornings. I did augment with down booties, long underwear, and an extra shirt. I was a touch warmer the second night as I learned how to position myself in the bag. I used a Windom hood the first night, but switched to a light skullcap the second night and was more comfortable.
As for the sleeping pad attachment system, I'm not a fan. Trying to get the little notch on the cord when your hands are frozen is well-nigh impossible. The hooks went on just fine, and in the end I found that, given my Wide quilt option, I was able to avoid any cold spots even without getting fully latched in. Instead of the notches, I'd rather see a simple click-snap (like they use to keep gloves together) on the quilt, with a series of partner snaps permanently attached to the sleeping pad cord. Yes, that would add a bit of weight, but you could actually use them when your hands are stiff. As it stands now I'd just as soon forego the clips.
I'll reserve the Windom hood for nights below 20. I'm thinking I could probably get this kit down to the low teens with 2 layers of nightwear, the Windom hood, and a thin closed-cell torso pad underneath my NeoAir X-Therm (R=4.2). In that scenario I'd reserve my puffy to add a bit more warmth to my torso or shoulders.
As for quilt versus mummy, I'm a convert. I was able to easily roll over without having my face in the hood the mummy and wait for compressed down to re-loft. It was very nice to be able to change into hiking clothes partially underneath the quilt and easily get back in to warm up (not easily done with a mummy). I do hope that I won't regret not having a way to vent heat from the footbox in warmer temps that can occur on a shoulder season hike.
Je suis acheteur français, et je trouve vraiment pénible et gênant de ne pas avoir l'équivalent des valeurs en système international d'unité (SI), Grammes, centimètre, degrés Celsius etc...
Purchased a regular length/width Alsek for the Haute Route Pyrenees and late-summer/early-fall trips in the Canadian Rockies. I'm 5'10" and 150lb with a slim build. Construction seems excellent. This was my first quilt, and the light weight blew me away. So did the warmth (used with Nemo Tensor pad): most nights in the Pyrenees I struggled to dump enough heat. When things cooled down, really appreciated the conservative insulation. I used the the attachment system a few times, and found it both useful for warmth and intuitive to use. If I had to do it again I would probably get the wide version, which allows for easier tucking under when temperatures are on the cusp of wanting to use the attachment system. Also, would make it a little easier to share a cozy tent with someone you might want to snuggle with. Can't imagine going back to a sleeping bag after this.
Perfecto. I am 5’9 @ 180 lbs. ordered a reg/wide. Happy to have a little extra girth to alleviate cold air slipping in the sides. The bag is so dang light that extra ounce is quickly forgotten. Length is ideal without any compromise. The snap system @ neck closure is bombproof and really can make things snuggly warm if needed. On the fence between Alsek and Sawatch; will layer up if reqd or maybe just buy a Sawatch later. Alsek is good all rounder. The ‘new’ phone pocket is ok but superfluous to a piece of kit that is minimalism personified. Have not found the need for attachment ‘options to sleep pad, perhaps due to extra width. One less thing to fret over when dark and sleepy. I just tuck in the bag if feeling a cold spot and nod off. Snug as a bug in a rug. What to improve? Hmm… coyote brown or drab olive might be nice. Also… excellent customer service on phone with Trey. If busy, left message, with a call back very soon. Unusual and appreciated.
Length: This refers to the maximum height of the user. For example, if you are 6’ tall, you should comfortably fit in our 6’ length, and the collar will loosely come up to your chin. If you are a stomach sleeper, you’ll want to add a few inches to your height since your toes will be pointed away from you, essentially making you “taller.”
Width: If your shoulder circumference measurement (around the widest part of your chest + arms) is 51” or greater, you’ll need to select a wide size. You can opt for a wide even if you don’t meet that measurement. Just keep in mind that if there is too much dead air space inside the quilt, you might sleep a little colder.
Fill Power (FP): Down with a higher FP number provides more loft, so we need less of it to achieve a certain temperature rating. Therefore, the finished weight of a quilt filled with a 900 FP option will be slightly lighter than one filled with the 850 FP down, but they would be equally as warm.
Duck vs Goose: Duck down is more readily available than goose, so it is less expensive. There are no performance differences, and one will not make your quilt warmer than the other. Note that our duck down is only available as an 850 FP, so the quilt would be slightly heavier (see above).
HyperDry: This treatment helps the down maintain its loft better in damp conditions, and helps it dry out faster if it does get wet. The HyperDry treatment is most useful for folks who will encounter a lot of humidity or rain, or will sleep numerous successive nights with lows in the teens (°F).
