MARCHWAY Floating Waterproof Dry Bag Backpack, Roll Top, 5L/10L/20L/30L/40L

Overall, this is a great product. I work as a commercial seaplane pilot in the Bahamas, and wanted to upgrade my pilot bag to something waterproof, high visibility, and easy to carry/use. I ended up buying two of these bags: One was the 10L Hi-Vis Orange bag, and the other was the 20L Hi-Vis Yellow bag. I'll review both, starting with the 10L. 10L Bag: One thing you have to keep in mind with these bags is that they require 3-4 folds before you buckle the top closed to be effectively waterproof. What this means is that the bags are not as tall as you would think just looking at them in the package. I haven't actually attempted to measure the size of the bag when it is closed to see if it is actually 10L, but I would assume the overall space is reduced when closed (especially depending on how many folds you put in before closing it). With this being said, I can easily recommend the 10L for 3-4 medium sized handheld items (which I will specify now). For myself, I stored an aviation headset bag (measures about 6x4x10 [LxWxH]), a pilot logbook (6x2x12), my passport booklet, sunscreen, and an ipad mini. It was snug, but I could still get 3 rolls and latch the bag shut without any problems. Initially this was okay, but I wanted a little more room so that I could bring extra items like extra clothes, bandages, water, etc. as my days are long and spent in the sun. Now, I carry the 10L bag with me (Folded up nicely in my 20L bag) as an extra buoy if I have to cut an anchor line. These bags are air tight when closed properly and will hold any residual air inside once closed. All I have to do now is blow a little air in the bag, roll it, latch it, and it is a buoy or flotation device. The 10L bag is great if you don't have TOO much stuff to carry, but I'd caution you to go with the larger option if you are unsure and aren't confined to a small space for the bag. 20L Bag: The 20L bag functions the same way as the 10L, but supplies twice the space. I have plenty of room for all of the items mentioned above, and some. An added benefit is that the 20L comes with 2 straps instead of one, so I can wear it as a backpack when walking around the islands. Beyond that, there really isn't much difference at all between the bags. Pros: -The bags are simple to use and versatile -The color options are great, especially if your use for the bag may end up with the bag falling overboard -The bags will float when sealed properly -No water has been found in my bags yet (but I'd still add extra caution and seal anything you absolutely can't get wet in another plastic bag as well) Cons: -Folding the bag over eliminates some space, which means you need to plan your space utilization carefully if you want a waterproof bag! -The bag is not designed to be submerged for more than a few seconds... it is waterproof when floating (which is what it does). If you force it underwater for too long, the pressure of the water may force some liquid into the bag Overall, I'd say this is a great, CHEAP, and simple product. Take it from someone who's out on the ocean all day: it works!

Bought the 30L size for a weekend motorcycle trip during which there was a chance of rain. Luckily there wasn’t a downpour but did get some sprinkles and a lot of road dust/grime. This bag kept everything clean and dry. I put it on my passenger seat and passed the straps underneath, securing by tightening the straps and using one bungee cord across the top for extra insurance. Did the job I needed it for. It held two changes of clothes, extra socks, and toiletry bag easily. There wasn’t quite enough room to also pack my CPAP machine but I had room for it elsewhere on the bike. The CPAP case does fit into the bag on its own, with room for a few other items, though. I’ll have to play with the configuration to see if I can get it all in. The 50L might work but it would have been too big. Overall a good product and a good buy.

I really like this bag. I got the 20L/Flower pattern. It looks good and carries a good amount of stuff - big enough for a towel, food, water bottle, sunscreen. I got it for a day of kayaking. It's easily water resistant. I also took it on a trip to the Caribbean and it was great for both the beach and snorkeling. Almost wish now I had gotten a bigger size, but this size is pretty convenient for most of my needs.

Great bag, great price. Kept everything dry while in the water.

Holds 4x4dd and 3x3dd tarps , all my stakes with linelocks and cordage and alps lynx 2 footprint..top still has to be rolled down..plenty big enough..if I put sleeping bag in first I could fit all ..has detachable shoulder straps..no way that material can let water thru .I use an eberlestock F1 mainframe with vapor 5000 pack zipped to 2 v2 batwings .this dry bag and contents compresses between frame and pack..I don't open pack nor detach anything .pull tarps out and setup .throw everything else under it .and pour a cold drink from the thermos..

Okay, I've gotta be real: I'm usually the one people trust to keep stuff safe. So, on my recent rafting trip, I found myself being the guardian of not just my essentials but EVERYONE's valuables. And trust me, that’s a level of responsibility I wasn't quite prepared for. But enter the MARCHWAY Floating Waterproof Dry Bag – and, boy, did it deliver! Here's the deal. This isn't your run-of-the-mill bag. Made from ripstop tarpaulin, it's built to withstand tears, rips, and punctures. It's like the superhero of dry bags. The roll-top closure system? Airtight. Even when we splashed, bumped, and got a bit wild on the water, everything inside stayed bone dry. Phones, wallets, keys – all safe and sound. And that's not just me saying it – everything from phones to towels to a change of clothes stayed dry for my fellow adventurers too. Now, a quick PSA: If you're new to the world of dry bags (like I once was), make sure you get the lowdown on how to seal it properly. I had a rookie mistake with a different bag once, and let's just say, wet socks aren't fun. But once you've got the hang of it, the MARCHWAY bag is a breeze to use. The versatility? Top-notch. It floats, so you don't lose sight of your stuff. Whether you're kayaking, beaching, or climbing snowy mountains, it's got your back (literally, if you wear it like a backpack). And with sizes ranging from 5L to 40L, there's one for every kind of adventurer. In a nutshell? If you're heading outdoors and need to keep your stuff safe, dry, and within reach, the MARCHWAY Floating Waterproof Dry Bag is a no-brainer. It's got the durability, style, and versatility down pat. Happy adventuring, folks! 🛶🏔🌟

Love this bag so much!! So much room for all my belongings to go to the lake!

I bought this for an Alaska trip that included an ocean kayaking excursion. It went with me into Sitka Sound and worked perfectly for the excursion. I got the 20-liter size, which was more than sufficient for the trip, and also allowed it to function well as a carry-on item during the flight home. On the kayak, the storage capacity of this bag allowed me to bring a 36-ounce Yeti Rambler water bottle, binoculars, thick gloves, a sunglasses case, and a wallet, with space left over to store a sweater or light jacket. Fortunately, its flotation capability didn’t get tested since there was no capsizing during this excursion. The material feels thick and durable, and I’m confident that it would float if it got dropped overboard. It’s easy to use and seal by rolling the top band a few times and clipping the buckles together. I would recommend this 20-literally size for a day-trip or partial-day outing on kayaks. It could fit at your feet if needed, but worked perfectly by securing it to the bungee cord rigging that was attached to the kayak hull.

Excellent on holiday, and can be locked with a padlock between the rings used to attach the strap - very handy for on the beach!

Bought as a Christmas present. My friend loves it

Comes with double straps for use as a backpack. Solid build.

Waterproof as it says and has strong material

I try it few times:, all the time the same result: water inside the bag. Unfortunately, it is not waterproof. Even though I always closed it very carefully, water entered, although not a lot, but enough to ruin what was inside. After the third day, it already started to have cracks. Terrible
