Great quilt. I was torn between the regular and wide but went for the wide in the end for extra comfort (despite the weight increase). Build quality is fantastic and quilt feels very warm on the limited nights I've used it so far. Highly recommended.
My son has already slept outside this winter in his Alsek Quilt and loves it! He's looking forward to many camping trips with it.
I got my Alsek 22 in the fall of 2016. I just got back from Northern Michigan in November 2021 and I still love this quilt. I have spent over 300 nights in this quilt and it has never let me down. That said I wish I got the 30 degree bag because I am a hot sleeper. I have used this quilt down to the mid 20s (-5c) and never gotten cold, and I sleep in the buff. I have woke to 4" of snow on the tent, freezing rain, frost on everything and I was still sweating lightly in the Alsek. I have never used the strap system and actually cut the connectors off because I haven't found I need them.
I am a gear junky that is not very cost conscience, I am constantly buying and trying new gear. In the last six years there is only two pieces of gear I have not considered replacing. #1 My Zpacks Duplex, #2 my Katabatic Gear quilt... well actually I did get a 40deg Chisos for summer use because the Alsek is too hot above about 45deg.
Only negative I can see is no option for customization other than more down fill. I would love to be able to buy one without the strap system, but that will not stop me from buying another Katabatic quilt. I will just cut the connectors off when it comes in the mail.
Of all the backpacking gear I have, my Alsek is the single best item. I’ve used it for over 3 years now, on numerous overnight and longer trips from Appalachia, to the PNW coast, Glacier NP, Maroon Bells, the Winds, and the Pemi Loop. I’m usually in a hammock, but I’ve also used it on the ground. When it’s colder I use the snap, which causes the quilt to nicely snug up around my shoulders and back. I’ve not used the pad straps. If I was on a pad more often I might, but so far it hasn’t been necessary.
The design and craftsmanship are excellent, and the materials and sewing have held up outstandingly.
For comparison, I’m 6’ 4”, 250 pounds and have the long, wide version.
Like I said, this is the best piece of gear I own. And that’s not for lack of having a well stocked inventory.
I've had my Alsek quilt for about 18 months now and used it on, I think, 4 trips / 10ish nights so far. (Fewer than I'd have liked, but, ahem, pandemic.) Therefore I figure I owe a review. TL;DR version: I highly recommend this quilt.
I've used the quilt in tents with and without a partner, with lows mostly in the upper 30's and lower 40's. Fortunately for me, weather on all these trips was great, but that does mean I've not pushed toward the rating of the quilt yet. That said, I've been very warm every time and had no trouble with drafts or cold spots. (In the 40's I'm almost too warm; I have to go hatless to vent some heat!) Impressively, the quilt stays snuggly on top even when I don't bother to use the pad straps (which, at these temps, is usually) or fasten the collar, whether I'm back, stomach, or side sleeping. In short, I've been plenty warm just sort of flopping it over me. This gives me confidence that it will perform down to 22°F as rated if I were to bundle up a little more.
The quality is very high, and no down shedding yet (unlike a competitor's quilt I've owned). The fabric is soft. Weight was as advertised and compression is good. The only thing I regret is that mine is brown, and now they come in the niftier blue color. :)
For reference, I'm 5' 11" and bought the 6' 6" regular version. Plenty of room without dead spots. (I sized up for stomach sleeping. I probably could have gone with the 6' version safely but I don't regret the extra length.) I'm skinny, so I typically sleep a little cold. This quilt is the first sleeping bag I've owned that, for me, seems to have a correct temp rating.
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 49” 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).
