    keep your sh*t dry

    • Familiarity: I've used it several times

    These dry bags are awesome. They are lightweight yet (still feel pretty durable), and keep their contents dry. They come in many sizes so they are super versatile. I use the 13L as a food bag for 3-5 day backpacking trips and the 8L for my 30 degree down sleeping bag. These bags are a great way to waterproof your backpacking setup, and could be also be used as stuffsacks inside a larger drybag on river trips, although they don't seem like they are durable enough to be used on their own on river trips.

    1L - First Aid Kit ; 13L - Misc Hiking

    • Familiarity: I've put it through the wringer

    I use the 1L size to make my own first aid kit, and the 13L to store my food or clothes while backpacking. It likely wouldn't keep everything bone dry in the event of submersion, but that isn't what I plan to do with these, nor is that what the product is intended for so I'm fine with that.

    1L is small, after compressing the air out and rolling it closed, it's slightly smaller than a Nalgene bottle. This means it's small enough that I never won't bring it with me, which is exactly what I was looking for. I'm not a guide, so my kit only has necessities for a few days: headlamp, irrigation syringe, bandages, gauze, alcohol pads, antibiotic ointment, naproxene, antihistamine, loperamide, aspirin, tweezers and a multi-tool fit just fine.

    The 13L will hold 5 days of food, barely (for me). I'm a double serving freeze dried dinner eater, have a freeze dried breakfast, and usually snack for lunch. If you eat less, or are creative with how you package, you may be able to do a 9L bag for 5 days, but I can barely squeeze it all in the 13.

    I got the first aid 1L in red so I always know it's my emergency kit. Maybe not the best color to pick if you or your partner are color blind.

    2L green

    • Familiarity: I've used it several times

    Like the bright color! Bought the 2L as a little map, phone, and book holder for when Im kayaking or hiking in rainy conditions. Perfect size for just that. Great value buy as well! Really good quality.

    Gigantic Size - Dot it all bag

    • Familiarity: I've used it several times

    The 20L Size is just gigantic! You can fit a whole travel clothing and have some room to spare. I use this to pack all my wet/dirty triathlon clothes and keep them separate from any clean clothes left when I got for competitions. It keeps everything separated cleanly, including smells which is great.

    A Must Have!

    • Familiarity: I've used it several times

    This is one of my go to food bags for backpacking or whitewater trips. I can typically carry up to 5-6 days of food quite easily in this sack. Sea to Summit is making some of the highest quality dry sacks on the market today. Mine has not seen too many miles but I have spoken with thru hikers that have had this dry sack last all 2200 miles of the AT. Could also be used for a lightweight cold weather sleeping bag or topquilt.

    Super Versatile

    • Familiarity: I've put it through the wringer

    Everyone should own several dry sacks. They come in handy all the time - obvious for taking a hiking or rafting trip to keep important stuff dry, but also for regular travel to throw in your luggage to keep things like your toiletries kit from messing up the rest of your clothes or put store dirty clothes in and then squish them down to take up less space. When I work out during work travel on a day I head home, I throw all my sweaty gear in to keep the rest of my bag clean, and just throw the entire thing in the washer when I get home.

    So necessary

      these dry sacks are so necessary for all sorts of packing needs. From minimizing space, making the most of its volume capacity...i use these from everything to camping gear, packing clothes for trips, and just anytime i need to use the most of my allowed space and pack as much as I can into the bag. :) Being waterproof is just another awesome plus. Definitely recommend getting a few of these!

      It does what it claims

      • Familiarity: I've used it several times

      Bought the 20L one. Great size, nice colors, easy to open/close. Keeps your stuff from getting wet indeed. I use it mostly for gym/swimming classes, when I'm done, I just throw the wet towel/jammer/shorts/shirt/etc in the bag and forget about them till I get home, the other stuff outside the bag is safe from getting wet (your car seats, backpack, etc.)

      Need a Dry Sack, Look No Further

      • Familiarity: I've used it several times

      Sea to Summit makes a great product and I have always been happy with my purchases from them. This sack is no different. These are seriously life savers when you are camping, and need to save some space or you want to keep your clothes dry. The nylon is strong, and durable even when you abuse it. I never worrying about tearing this sack, even when I load it up. Do yourself and your gear a favor and buy one, the peace of mind alone is worth the price!

      It might keep stuff dry?

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

      So. I havent had to make sure it works yet luckily. havent dropped it in the water or anything. Good thing because I read the tag after my trip and it basically said "Don't submerge this dry sack because your stuff will get wet" Isnt the point of a DRY sack to keep stuff dry? That being said, it will absolutely work better than nothing and probably much better than keeping your phone in a ziploc bag.

      Great for Hunting Gear

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

      I bought this bag to keep my hunting clothes stored and protected against any scent that I don't want in my clothes while I'm out hunting. I packed them with a scent wafer and it's worked better than I expected. I would recommend this bag to anyone who needs to store their hunting gear until the next season.

      Not just one

      • Familiarity: I've put it through the wringer

      I have a 2 L, 4L, and next will be an 8L or 20L. I use them camping, hiking, SUPing, traveling, boating and can't wait to find more uses. As stated below, I use my bags to keep items dry, transport garbage, store dirty laundry. The D-ring is a nice feature to easily clip on to packs, boards, ect.

      light and dry

      • Familiarity: I've put it through the wringer

      Sea to Summit hit a home run for a lightweight dry sack. In the 13L I was able to pack all of my clothing for a six day bike packing trip along with my compact sleeping pad, with room to spare.

      light and dry

      Just as advertised

      • Familiarity: I've put it through the wringer

      I've been using these bags on my motorcycle trips for over a year.
      Perfect for my sleeping bag which didn't come with a waterproof bag. I've ran it through countless rainstorms strapped to my bike where I've been soaked to the bone but I always get a nice dry bag at the end of the day.
      They also work well as compression sacks if you get the knee press method down which helps a ton with pressing down extra clothes.

      Not dry

        I think this bag would be great for food storage or something else, but tried taking it down the river on a float and everything was soaking wet. Wouldn't recommend for electronics or things that truly need to remain dry.

        Looking for a bag to slide onto an outdoor punching bag to protect from So. California Sun also rain proof would be nice.

        I need something to cover 42.5 inch long punching bag .

        I am looking for a bag to store my laptop...

        I am looking for a bag to store my laptop in while in the extremely humid rain forest this summer. I won't be bringing it out into the forest much, I just need a bag that I can keep my laptop in that will keep it dry from the moisture while I am not using it. Is this my best option?

        Have you measured the dimensions of your laptop? I would be concerned about it even fitting into one of these dry sacks, unless it's a netbook. The maximum width on the largest of these is 12", so I believe your best bet would be finding something along the lines of a weatherproof bike carrier bag or something like that. The moisture will be a problem, certainly, and more so if you have it close to your body for extended periods of time, so be careful about that as well. However, unless you have a VERY small laptop (such as the aforementioned netbook option), I would dissuade you from even bothering to purchase this.

        Hope this helps, though perhaps someone may follow behind me and posit alternative reasons for purchase that I may not have thought of.
