This is a super great compression sack, that will get your down feather sleeping bag to the size of a grapefruit. It was a great decision buying this with my western mountaineering summerlite sleeping bag. I am extremely happy with this purchase! Go buy one now, from moosejaw. Buy it.
These bags are great! They are light weight compress to very small sizes and are very durable. My oldest one is over 5 years old and its still in great condition. Slick surface also makes them easy to slide in your bag.
I took this on a two-week camping trip in Africa. I stubbornly decided I would do the entire trip with a 33L backpack - tent and all! I stuffed my Big Agnes Fly Creek 2-person tent, my Mountain Hardwear Ultralamina sleeping bag, and my pack towel in this thing and crammed it into the bottom of my bag. For the record, that's roughly 10 pounds of crap in a 5 pound bag. Basically, I abused it like a red headed step child every day for two weeks. Just get it - a solid stuff sack is a traveler's best friend.
Excellent compression sack. Very light. Surprisingly durable. Can really crank down on the webbing to super compress it. Takes up virtually no space or weight in the pack. I will be ordering more soon!
I have a 10 year old sleeping bag (but it still works reallllly good i swear) that my brother borrowed and lost the stuff sack for. I have never use a compression sack for my sleeping bage before but i love this one. It gets my bag super small.
At first touch, this bag is crazy thin. However, it is quite durable as I use it to carry a three person tent and rainfly. This is definitely the best compression sack I have used.
I take these wonderful, waterproof, Cordura sacks on every trip of mine, and my gear stays compressed in my pack, and DRY. Works great to store camp shoes, so when you stop, you know you will have some dry comfortable shoes.
The material is scary thin at first, but it takes some abuse. That being said, you should take care not to snag it on sharper things in your pack, i.e. stakes or a cook pot lid... But use common sense, and it will last for years. I use mine for clothes, and it makes a silky smooth pillow if you finagle the buckles out of your way

I recently replaced some ancient heavy compression sacks with these. I got an XS for my down jacket, and a M for my 25 degree Western Mountaineering Bag. The M lasted only about 15 days (in decently rough desert conditions). The ultrasil has good tear strength, but it's weakness is anything pointy! By the end of that 2 weeks, there were at least 5 decent small holes in it, the tiny cord lock and one buckle broke. It doesn't seem up to the task of being a sleeping bag compression sack. However, I still use the XS with my down jacket, as I compress it, and keep it in a light drybag with other clothes. These work great for that, but seem to be lacking when used in rougher conditions.
