    Awesome Dry Bag for an even better price

    • Familiarity: I've used it several times

    This SealLine dry bag is so great. It is very durable, definitely waterproof, and it does it's job perfectly. All of that for under $15 is pretty remarkable if you ask me! I have two of them in the 10L and fit all of my clothes that I take for a couple day backpacking trip perfectly. Fill them up with clothes, food, your tent, or pretty much anything your looking to keep dry and you're ready to go. Fit great in just about any backpacking style backpack, and perform better than any other expensive dry bag i've ever tried. Would highly recommend!

    Great durable dry bag

      This is a great bag if you're looking for a durable dry bag. Its a cordura style nylon that is laminated on the inside, then the seams are sealed. I've hung it by the handle in the rain without leaks, its been thrown about in the bottom of the boat, left outside on the ground in a puddle during thunderstorms, floated through rapids, and otherwise thrown around. So far it hasn't suffered a scratch, and hasn't leaked. Unless you plan on dragging your bag through rocks, I don't see any reason to get a tougher bag. Especially when the black canyon bags weigh more than twice as much.

      typical water bag

        I've burried this bag deep in the surf during a beach launch, stuff flying all over the place and the camera and clothes inside remaind dry. There is an extra flap to this bag that is designed to keep things air tight.

        I've even used this bag as a rescue throw. I think that if I was going to buy a dry bag as big as 60L, I would probably buy something made with a thicker double sided PVC material. 60L size would work fine inside a backpack or other bag that would be offering the abrasive strength.

        Has anyone tried using a 60L as a pack liner? I am looking for efficient ways to keep my pack contents dry on rainy weekends in the Pacific NW.

        Is the width dimension measured laying flat or a diameter?

        Is the length dimension measured rolled and sealed?

        Best Answer

        I must admit, my curiosity was piqued by this question, and while I cannot say that the dry sack/stuff sack used is exactly a control variable, I found some interesting things that differed from the claimed specs, so they may be of some help to you.

        So I have a Medium size Sea-to-Summit eVent Dry sack, with claimed dimensions of 8 x 18 inches.

        At the bottom of the stuff sack, I measured the diameter and found it to be the advertised 8 inches across. However, at the top, taking the same measurement, I found it to be 10 inches, and then when I laid the sack flat and measured side to side, I got a measurement of 12 inches.

        With regards to length, as opposed to the 18 inches claimed (I don't know if this is meant to represent, say one (or two or three) rolls of the top), when lain flat, I got a measurement of 20 inches. I assume that 18 inch measurement takes into account the S2S minimum recommendation of 3 rolls of the top to ensure that whatever is contained within stays dry, so take that 20 inch measurement I found with a grain of salt.

        In any case, I would have to guess the measurements that are provided would take into account rolls of the top (thus deducting inches from the overall length) and perhaps take into account items inside the bag (thus deducting inches from the overall width).

        Hope this helped!

        I am going on a three day raft trip, only...

        I am going on a three day raft trip, only taking a sleeping pad, sleeping bag and a change of clothes. What size of dry bag would suffice? This is my first raft trip and it's a short one so I won't have a ton of stuff.

        Hey Staci,

        It all depends on a couple of factors. First, is the temperature rating and insulation material of your sleeping bag. A 30 degree down bag is a lot different than a 30 degree synthetic in terms of compressability. Second, are you planning on using a separate compression sack. I'd say if you're going to be putting your bag and clothing in a compressions sack, then I'd say you might be able to squeeze it in a 35L but it would be really tight. The 60L is probably the way you want to go.

        I'd like to enclose an item that is (Dimensions WxHxD): 12.6in. x 9.1in. x 5.0in [Epson EMP-DM1 3LCD Projector].

        How big would my Storm Sack have to be (2.5L/5L/10L)?

        Are the length dimensions for closed tight / sealed?

        My down bag's stuff sack size is 8x17....

        My down bag's stuff sack size is 8x17. What size dry sack should I get? Can I just put the bag in the dry sack without the stuff sack or not?

        I just go straight into the dry bag. You can roll these down and "compress" your bag pretty well with them. Down is a lot easier to compress than synthetic in my opinion. Keep in mind you'll need to Roll the closer a few times to keep the contents dry (but you probably already knew that).

        9 x 21in [25L] = Might be a tight fit depends on if your 8x17 leaves room to compress or is pretty tight to start with.

        7 x 25in [35L] = Would probably fit pretty well.

        10 x 28.5in [60L] = Would be plenty big and leave some room for other stuff.
