    Good Bag

    • Familiarity: I've used it several times

    Works well, nicely detailed and featured. I love the hang loop and the white interior. The concealed, two-sided cord lock is clever, but a little tricky to do with gloves or only 1.5 hands when you are trying to wrestle other stuff. The red color is much more of a "rust" to my eye, but I actually like it better for that.

    Pretty waterproof

    • Familiarity: I've used it several times

    Honestly, after having so many non-roll top stuff sacks leak, I was expecting at least some water to get in. So far, I have been wrong. I filled this stuff sack and completely submerged it, and only a few drops got in, maybe from when I was opening it. The stuff sack is larger than I thought it'd be and the inside is white so it's super easy to find little things left behind. It's a really great value, especially for the price, and I definitely recommend it.

    Great for hammock quilt and under quilt

    • Familiarity: I've used it once or twice and have initial impressions

    I bought 2 of these in size Large for my full length 0 degree hammock top quilt and under quilt, both with about 3.5" of loft. The quilts stuff in easily with good compression but not so much that it crushes the down.

    I usually go for the ultralight silnylon stuff sacks, but at 2.3 oz on my scale these offer better protection and can be used as sturdy gear storage bags clipped to my hammock.

    Excellent stuck sack

    • Familiarity: I've used it several times

    Have used the stuff sack (medium size) to manage my in-pack clothing. The medium fit perfectly at the top of your backpack. You can take the sack out of your pack when unpacking and set it down anywhere - the material keeps your contents dry.

    Large is the perfect size for a down bag

    • Familiarity: I've used it once or twice and have initial impressions

    I purchased this stuff sack to replace a disintegrating bag for a three-season down sleeping bag. When I received it, I realized it is smaller than the one I was replacing, but since the bag stuffs down so well, it's actually an improvement.

    The quality of construction is excellent, and the grab handle on the bottom is really handy for unpacking the bag.

    Well made, lightweight.

    • Familiarity: I've used it once or twice and have initial impressions

    I bought the 20L to have on hand as an extra bag, especially when wanting to keep things dry (like a fresh change of clothes when you've had enough and just need to break out some clean and dry clothes. ;) ) It's large enough to go around my down sleeping bag and still have room for a change of clothes, or it will hold several changes without the sleeping bag. It's well made and lightweight.

    White on the inside!

    • Familiarity: I've put it through the wringer

    What really sets this stuff sack apart from other waterproof burly durable stuff sacks (OR Durable, Podsacs Deluxe) is that the inside is WHITE! This is sooo helpful when you're looking for a small item. The dark gray color linings of other sacks makes hunting for items a chore. Otherwise, it works as advertised, but so do my other quality stuff sacks! It doesn't have the external daisy chain of the OR Durable sack, but how often do you need that feature?

    My one complaint is that the XS sacks are long and narrow , and this can make it difficult to remove small items or stuff small down jackets. Podsac Deluxe is my go-to small stuff sack due to its shorter and wider shape.


      I purchased a 15L green and 20L red. I really love the green color and 15L is really an ideal size. Between the 15L and 20L, I can long-term store my cold weather and warm weather sleeping kits. I recently went backpacking with an army surplus Alice frame strapped with this 20L, 15L and a Marmott Kompressor. These bags were perfect, but I'm now on the hunt for a more comfortable frame.


        These are great. My pack is not waterproof, so I make sure everything I put in it is in some kind of waterproof bag. These work great for all the random items or clothing that you might want to put in your pack and keep dry. I have 2 XXS's and a XS. I use one XXS for my first aid kit and the other XXS for all my random camping items that don't have another place to go. The XS I usually put my food in. I've not actually gotten to test them in rainy conditions yet, but I filled one with a bunch of stuff and ran the sink over it for a while and it was totally dry, so I trust the waterproofing. I love how the the cinch cord is contained within a sleeve so its not hanging out loose. Quality construction on these things.

        Got the variety pack

          I recently ordered one of every size from XS-L. I wanted to get enough that I'd be covered in most situations. The small and medium ones will work great for jackets and food and stuff, and the bigger ones will fit all the clothes I can pack plus my sleeping bag, which has its own compression sack but it's not waterproof. These bags are surprisingly tough and light and they seem very waterproof. I like how the cinches for the drawstring are incorporated into the collar of the bag (if you look at it in the pictures you can see what I mean), how there's that flap at the top to act as a lid and help to keep water out, and I like the webbing strap on the bottom and the little tab on the top that you can thread the drawstring through to make it extra-secure or you can use it to hang the bag while you're digging around inside it for a pair of socks or something, though I'm not sure how much weight that little tab can hold. If it's hypalon, which it seems to be to me, then it's probably pretty strong.
          So, I'm looking forward to these things keeping my gear dry and organized and making packing a lot easier. Can't wait to take them on adventures with me!

          Stuff sack

          Fully load

          Stuff sack

          I filled my bag with 8 pair of socks, or 4 pair of socks and 4 boxers, that means that you can pack it up and be ready for 4 days of action.

          The material is kind of water proof, so it's perfect of your dirty clothes XD

          ..hope it helps..

          My new favorite.

            Good bags. I bought these to use in addition to a rain cover for my backpack. a few extra ounces is worth the security of having a dry sleeping bag and clothes. Just don't get so extreme as to totally submerging your pack & you'll be OK. Also, I like the fact that they are more heavy duty than standard stuff sacks.

            Little is really little.

              Super light weight and really waterproof these are great for small stuff in the small sizes. I would recommend seeing this before buying unless you are really good at mentally judging the space you need. I would recommend also buying one size. They apppear to be pretty tough too.

              A Good Choice, IMO

                After buying dozens of stuff sacks from OR over the years, I've grown tired of the price increases, taking the daisychains off several models, taking the dust flaps off, ... just generally cheapening the product, while increasing the price. So, I wanted to try some Summit sacks.It's a win!! Good, straight sacks, very well made, and I think they're great.So, that's two traditional suppliers I've avoided this year (Black Diamond was the other, due to their anti-sale, anti-discounting practices.).I will stick with this product! Thanks!!

                Stuff sack included with my down bag is abit small for my liking, 5.4x10.7 ... I'm thinking of getting a small at 6.5x13 to allow the down to expand abit more while backpacking ... Anyone use these sacks for their down and can i trust it to keep my bag dry while hiking in a few days of bad rain ...

                Best Answer

                I use sealed stuff sacks for sensitive materials, including sleeping bags, when rain is the threat and it works out just fine. Same in the winter, when *everything* gets wet from freeze / thaw and use in a tent. However, if there is a chance of immersion, like a fall during a water crossing, I'd want something more secure, like one of Summits dry sacks. Then, *nothing* will touch your contents.

                Anyone used this for canyons? I go down...

                Anyone used this for canyons? I go down canyons regularly (which means diving into the water - 2-3 deep dives after jumping) and I am sick of hard plastic containers. This would be perfect if it is waterproof enough. Thanks,Enrique

                Best Answer

                I have not used this for canyons, but i have used this for kayaking. For the price, it's waterproof enough. However, after not too long, water starts to slowly seep through the small crevasses not perfectly sealed by this system. It seems like you're going to be putting this bag through a good bit of water exposure, so i'd recommend the sea to summit ultra-sil line. It's basically the same thing, but with the traditional dry sack seal. Hope that helps!
