Kepps stuff dry

  • Familiarity:I've used it several times

I have had mine about four or five months, and have noticed no signs of stress or undue wear. Keeps thigs dry, stuffs ddown, folds up, yada yada. Great price, good bag. Simple.

Great waterproof stuff sack

  • Familiarity:I've used it several times

Great stuff sack to use for your sleeping bag on a float trip or a camping trip in adverse weather. I bought the 15L and was able to fit my Northface zero degree bag in it which decreased the size of the bag significantly (The north face stuff sack that came with it was huge! and also wasn't cinch-able). Or you can fit a 30 degree bag and a small stove like the pocket rocket inside it as well to save space on a hike. The options a basically endless!

Perfect Compression Sack for the Price

  • Familiarity:I've put it through the wringer

Although I hesitated at first due to a few of the reviews posted regarding durability, I am glad I grabbed some because they are amazing. They compress well, they are durable, and they keep your gear dry. I would highly recommend picking up a few.

Will hold/compress anything!

    I bought all three sizes originally offered in this dry compression sack. I use the 10L for my 30 degree down sleeping back which I can fully cinch the compression straps down, if they were longer I could cinch them even farther. I use the 15L to hold my rainfly for my Stoic Alpine Suite 4 tent and the 20L to hold the actual tent itself. All these sacks have an internal draw cord where the roll top and compression straps meet to hold gear down while compressing and then rolling the top down. Great bags, really glad I got them, very versatile.

    Great comp sack

      Inexpensive, easy to use, and has withstood lots of abuse from me trying to compress the bejeezus out of my clothes. Never had any problems with leakage into the bag and it works great in very humid enivronments, keeping your stuff nice and dry. It takes a bit of care to really get a nice air-free pack but you can get two sacks for the price of one that has those air releases.

      have only used these for camping and personal travel so cannot speak to their durability/use in backpacking situations.

      Maybe not...

        I returned a 10L and 15L after the 10L tore at a compression strap on first use. Maybe the one i got was defective, but beyond that they're pretty bulky compared to other dry compression sacks I've used. They'd probably be good for sailing or boating, but i wouldn't recommend them for backpacking or mountaineering.

        Good Deal

        • Familiarity:I've used it several times

        Picked one of these on SAC. Got my my REI Sub Kilo +20 down bag AND a thermolite reactor liner into the 10 L Sac. Granted, I sit on it while I tighten the straps, and when I did this while buzzed the attachment point for one strap ripped but it still works fine and did not compromise the waterproofing.

        TIP: tighten each strap a little bit and rotate trough all 4 rather than cinching one down all the way.

        wasn't wanting a bag as heavy as this, but if you want heavy duty dry bag, this one is real solid. One con is that it doesn't breathe at all. Not sure if they can make dry bags that do breathe... anyway, if there is any moisture in the bag, it will condensate everything else you have in it.

        Worked great on my last raft trip!

          Recently went rafting on the upper Klamath through some class 3 and 4 rapids and this bag held up good! Everything inside was perfectly dry. The compression straps are not only nice for making the bag smaller, but you can use them to hook other things on; I looped my spare sandals though one strap and then used a carabiner to attach the bag to the raft. I like this design better than the "Stoic WPF Compression Sack"

          Not a great design

            As dry bag compression sacks go, this is not a great design. It does not have a purge valve or an air-permiable membrain to let the air out. It has a drawcord closure abuout 2/3 of the way up the inside of the bag, and the idea is that you put your items in, close the drawstring, and then compress the bag. Finally, you close the roll-top closure to make the bag waterproof. The internal draw string is not easy to use. It is a very cumbersome method. You can not compress the bag once the roll top is closed. The Sea to Summit bags are a much better design.

            Do these bags have a valve?

            Do these bags have a valve?

            This bag does not have a valve. It works sort of like a regular stuff sack. If you fold down the roll top portion of the sack, you'll find a draw cord that you can cinch. The compression straps are attached to this portion of the bag. So you cinch the cord tightly, then use the compression straps to compress the bag. Excess air is expelled through the top where the draw cord is. Once compressed, you then use the roll top portion of the bag which is welded to the main bag to make it water tight. It's kind of a weird method but works.
