Expanded 20L-40L: Full-capacity backpack Review: Durable & Visible - Update February 2026: I’ve owned this bag over 3 years now. It’s traveled with me to Roatan Honduras multiple times now and over 75 diving trips. I use it through the summer at home out on the boat as well. The bag keeps all my stuff dry and has held up very well! This is a very good quality bag. I took this on a scuba diving trip to Honduras, used it multiple times over course of two weeks everyday. Hauled my essential gear wallet, towel sunglasses, snack, drink etc. on an open bow diving boat shared by 6 other divers. To say everything gets wet is an understatement! This bag performed flawlessly, it’s built well and good quality I’d imagine I could do the same trip several dozen times and beyond and get the same performance. Kept everything dry and as an added bonus the orange color made it very easy to see amongst everything else that was a big plus! I’m very satisfied with this bag ! Review: Great Bag! - 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! ## Features - Tarpaulin - Imported - Built to Endure: Featuring a reinforced multi-layer construction, this dry bag delivers exceptional tear and abrasion resistance yet remains flexible. Its ruggedness is backed by expertly welded seams, heavy-duty buckles, sturdy straps, and robust stitching. Designed to withstand rock scrapes and harsh conditions, it guarantees your gear stays protected and dry on every water adventure. - Superior Waterproofing: The roll-top closure creates a watertight seal. Its round bottom helps you capture air quickly: simply spread the bottom open, roll the top down 3 to 5 times, and buckle. The trapped air blocks water and provides buoyancy. Keeps your gear dry in rapids, waves, snow, and sand. Designed for all common wet conditions but not for extended submersion. - Multiple Sizes & Colors: A range from 5L to 40L suits any activity. 5L/10L are ideal for light trips and feature an adjustable, removable shoulder strap for cross-body carry. For heavier loads, 20L to 40L have backpack straps for even weight distribution, as a waterproof backpack. Every size folds into its own compact pouch. Choose from classic darks to vibrant brights to match your style. - Stays Afloat & Secure: When properly sealed and not overloaded, the dry sack floats visibly on the water, making your gear easy to spot and quick to retrieve. A reinforced D-ring and strap let you fasten the bag to your boat or kayak, keeping your belongings secure and within reach, so you can fully embrace the thrill of the outdoors. - Versatile Utility: Engineered for rugged durability and reliable waterproof protection, this bag is essential for any aquatic adventure. Ideal for paddling, sailing, surfing, canoeing, or river tubing, as well as beach trips and water park outings. When rain rolls in, it also serves as a dependable waterproof bag for traveling, climbing, or hunting, keeping your gear dry no matter the weather. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01LXBOVD1 | | Best Sellers Rank | #2,307 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #11 in Marine Dry Bags | | Brand Name | MARCHWAY | | Capacity | 20 Liters | | Closure Type | Buckle | | Color | Black | | Customer Reviews | 4.7 out of 5 stars 33,983 Reviews | | Handle Type | Web Handle | | Item Dimensions L x W x H | 9.5"L x 9.5"W x 14.6"H | | Item Type Name | Marine Dry Bags | | Item Weight | 0.95 Pounds | | Manufacturer | MARCHWAY | | Manufacturer Part Number | WDB20LBLA | | Material Type | Polyvinyl Chloride (PVC) | | Model Number | WDB20LBLA | | Number of Compartments | 1 | | Pattern | Solid | | Size | 20L | | Strap Type | Adjustable,Cross-body,Removable,Shoulder Strap | | Style Name | Backpack | | Unit Count | 1 Count | ## Images ![MARCHWAY Floating Waterproof Dry Bag Backpack 5L/10L/20L/30L/40L, Roll Top Sack Keeps Gear Dry for Kayaking, Rafting, Boating, Swimming, Camping, Hiking, Beach, Fishing - Image 1](https://m.media-amazon.com/images/I/71GwAzHWwfL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: How many beers will the 20L hold in it? Also is the strap strong enough to hold this full of beers?** A: The 20L is about 15 inches. If you did a nice circular stack with the cans you might be able to fit a little more than a 12 pack. Or do a circular stack and fill the middle with ice to keep them cold.πŸ˜‰ **Q: What are the dimensions on the 40L?** A: 40L size is Height 16.9 x Bottom Diameter 11.9 inches after top is rolled 4 times. **Q: How many pounds of kibble fits into 20L in these travel dog food bags?** A: Depending on the dog food brand, a bit less than a 10 pound bag. **Q: Family of 5 going on cruise, spending day on beach. What size would be best to carry everyones things? Do i need to 2?** A: The biggest is the 40L, I carried a cozy thick coleman sleeping bag (that is all). I think my answer will be: "It depends" in how you define things for 5 people. I hope the fact that that same size bag carried a sleeping bag will help you with an idea of how thick it is.

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.
