This was my first time using a quilt after years of feeling constricted in a mummy bag. I used the Alsek for the first time on the Lost Coast Trail in Northern CA for 3 nights this month in temperatures in the mid 30s. Conditions were wet and windy so definitely not ideal. I had condensation build up inside my single wall tent as I was sleeping by rivers and the ocean. I'm a cold sleeper but I stayed very warm and was much more comfortable being able to toss and turn. The outside of my quilt got water droplets on it but I brushed them off in the morning with none of it soaking in. The material is really nice quality and the pad attachment system for the straps allowed it to move with me in my sleep.
The same week another couple suffered severe hypothermia on the trail from the cold, wet, and windy conditions and had to call for help. This is a piece of quality gear that really proved itself on this trip. I recommend it and could have probably gone down another 10 degrees comfortably.
The quilt feels very nice. It came standard with things that are extra on other quilts- pad straps, storage bags, and stuff sack. I'm excited to use it soon.
Every piece of equipment I began with was ultimately upgrades to best accommodate comfort and reliability except for one. I was concerned from the beginning how durable this bag could be considering its weight but it proved to be extremely tough and resilient. I was never cold and after learning how to properly use the anti draft system, I never experienced drafts. My bag has an extra two ounces overfill and it couldn't have worked out better. This bag did not disappoint
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.
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...
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).
ExpeDry: This treatment helps the down maintain its loft better in damp conditions, and helps it dry out faster if it does get wet. The ExpeDry 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).
