Features
- Tarpaulin
- Imported
- Sturdy and Durable: Drybag is made of a ripstop tarpaulin that is resistant to wear, tear, puncture and remains flexible all year round. The seams are expertly welded and reinforced, strong and reliable. Heavy duty buckles, dense straps, secure stitching all enhance the bags overall strength. It won't wear easily even if it touches rocks and can be used for long time in harsh conditions, effectively keeping your gear dry, clean and safe.
- Superior Waterproofing: The roll-top seal ensures reliable watertightness, convenient and practical. You simply open the bag to let in as much air as possible, then roll the top down 3 to 5 times and clip the ends together. This keeps air in bag, prevents water from seeping in and allows bag to float. As long as the bag is not completely submerged, whether in rapids or other wet situations, it flawlessly keeps the contents dry, protecting them from water, snow and sand.
- Multiple Sizes and Colors: Sizes range from 5 to 40 liters to meet your different needs. 5L, 10L come with single adjustable and removable shoulder strap that can be carried across the body. 20L, 30L, 40L come with double straps that can be worn as a backpack. They can be folded into compact sizes for easy carrying and storage. Diverse color options make it easy to spot and differentiate with others.
- Floatable and Trackable: The dry sack can float on water without sinking after being rolled up and buckled, so you can quickly track and retrieve your stuff. The D-ring and strap on the bag make it easy to attach to the boat, keeping your stuff always with you without getting lost, allowing you to enjoy thrilling outdoor activities with peace of mind.
- Versatility: Its outstanding waterproof performance, durability and practical design make it a reliable companion on any water adventures, such as paddling, sailing, canoeing, surfing, river tubing, snowboarding, climbing, hunting, water park and beach trips. It can also be used as a simple bag for daily hiking or traveling during the rainy season.

Thick, waterproof, love the backpack straps. I got this to put my sleeping bag in to keep it dry. It's perfect and there's extra room for my small pillow. It can go smaller or bigger depending on how many times you roll the top down. Great product for the price.

This is a great bag and it's huge. The biggest bag fit towels and clothes for my family of three all day kayaking. Everything stayed dry and the bag didn't sweat like crazy either. The condensation is the worst TBH.

Bought this almost 6 years to the date! This thing is still holding up good! The straps are still in place, no leaking, or fading. The stritching is slowly starting to show wear, but still intact. 10L is perfect for one person's belongings (keys, wallet, phone, towel, sunscreen etc) or two or more people's belongings minus towels. I can fit a lot of stuff in this bag! Finally I purchased a 20L to store more after all this time!

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!

waterproof above water but not submersible. so good even for stuff like boating as long it floats. so basically a thick bag with a folding lid to prevent water from getting in. ordered the 40l which is the size of a big backpack.

Definitely does its job. Very easy to use/haul around and 100% waterproof. The size is awesome as well, can fit pretty much anything for a small day trip.
