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.

  • Keeps stuff dry
Size: 30L Color: Bright Yellow
Great quality and size! Took kayaking and travels well in the kayak. Holds a lot and keeps everything dry. Great designed product.

  • Durable!
Size: 20L Color: Orange
I've been very, very pleased with this bag. It's extremely durable, highly water resistant, and great value for money. I say "highly water resistant" because I've never completely submerged it. But it's been in plenty of wet conditions and I've never had wet clothes. Highly recommended!

  • Worked great for airline/river trip
Size: 40L Color: Orange
Loved the size and the backpack straps. This made for very easy transport both at the airport and on the river. Many dry bags have a single strap or worse one that snaps to the fold up portion stretching out the fold that needs to be water resistant. This has a solid grab handle, 2 full backpack straps, and a waste strap to hold it. Pros Works great for travel via air and river Color selection makes it easy to spot or not Simple grab handles and/or backpack straps Size fit my tent with space or my sleeping bag without space but not both. Cons While I had no real water intrusion there could be an improvement on the fold mechanism by adding some grippy material I have on other bags. A small pocket near the top inside would be a nice addition to prevent small items from falling to the bottom. Kept my stuff dry on the river for 7 days even after going through as a checked bag at tje airport. It was easy to spot at the airport or at camp site so it was not left behind. I will buy a few more of these. Great bags 5 star review. ... show more

  • First impressions is Wow
Size: 40L Color: Orange
bought nov 22 2022 as noted below, i sadly had to cut the shoulder straps off as this was always bought w intention of usage inside my 36l outdoor products hiking backpack well, this dry bag still works welll as the durable inner gab for my hiking backpack still keeps contents dry when needed helps reduce wear/tear on my hiking backpacks rather thin bottom will buy as a beach bag when i need a beach bag as im surrounded by 'em g8 bag g8 value oh and it is now juen 13th 2023 as of this review update, daily usage in my backpack note i have not clipped it shut daily - that only done a couple of times so cannot speak to buckle durability but they seem like your standard heavy duty plastic buckles so i dont see why they would ever fail no reason to buy sea to summit brand or similar as this bag is as good albeit far heavier but mabye this brand sells a lighter version/thinner version. agian this bag is made to be a stnadalone dry bag in a kayak etc i think. so much thicker than my 5L sea to summit bag (which has withstood 8 years of use as my 13 inch laoptop bag) Sadly the straps are not removable seriously i am sad about this as they are so thick and well made i was sad to cut them off lol why? cuz they are so heavy, so padded, that they added seemingly a half or 2/3 lb to my backpack this dry bag is perfect for my 36L hiking backpack with just 1 pocket. i put this 40L dry bag in and it def will add durability esp to bottom of my backpack as i carry electronics laptops etc in it i didnt want to cut the straps cuz of how nice n sturdy they seemed but had to the folding top and closure buckles seem heavy duty the bag is thick dunno thickness but a couple to seve mm?? my sea to summit 5L drybag is prob a 1/3 thick but then again thatbag is meant for inside a backpack or other bag and not as a standalone bag i thik. this orang 40l could easily last by itself - a reviewer in Hi said they've used it for a long time which is why i bought it - they said it lasted beaches salt air etc so i know it can last inside a backpack lol anit is same thickness if not more as my 20L dry bags from Outdoor products - a value brand you can get at walmart whose products all have LIFETIME warranty!!! OP products is also my backpack brand. i have 3 of their bakcpacks. they will always replace your item even years later. i knos cuuze ive done this on 2 items. one was for a frayed chsest strap & other leaking water puch. - point is this 40L orange bag seems as good as OP... will update over time and nope aint gonna fix typos lol ... show more

  • Kept my stuff dry
Size: 10L Color: Pink
I bought this in preparation for a kayaking trip. I ended up flipping my kayak and this kept my things dry! I had the bag attached to my kayak so I’m not sure if it floats as advertised. It does fill with air when you roll it up but seems to deflate a bit over time. I did notice a very small amount of water in my bag but I believe it was from my wet hands reaching inside. ... show more

  • Very useful, material is thick and very secure
Size: 30L Color: Teal
Let me tell you, it doesn't get more waterproof then this. this bag is so secure I mean it is a genius product. I would be absolutely shocked if someone were to tell me they got their belongings wet even when using this. It is very clear about how to use it and easy to pack and take with you or put in a suitcase which is really nice and it fits so many things in there. I used this in the rainforest in South America and I would just toss things in there like it was nothing and then roll it up, clamp it, and then I'm off. It looks very pretty and you can tell from the quality it is made of that it is very durable and the material is also tough so tearing a hole through it would be pretty hard. ... show more

  • Good quality dry bag at good price.
Size: 30L Color: Teal
This bag is a beautiful aqua blue color. If you're just using it around a pool or something, blue is fine, but if you're taking it out in a river or lake, I suggest getting a bright yellow or orange that would be easier to see if the bag gets separated from you (which almost happened to me). Bought the 30 liter dry bag thinking I needed the room for extra clothes/towels/shoes for myself and two friends, but we ended up not needing all that and used a small 10 liter bag instead that held just wallets, keys, a towel, and some snacks. The larger bag is great if you need it, but the material that these bags are made of is heavy, so the larger bags do make carrying more burdensome just from the extra weight of the bag itself. I thought I could just fold the larger bag down to be smaller, but the handle attached to the bag makes it impossible. This bag did allow for the full three turns minimum that most people recommend for dry bags, but the handle stops you from turning it down any more. I liked the extra loops on the lower front of the bag where you could tie things on, but I found it not as convenient as having a mesh pocket on the front like my other dry bag. The straps were basic, adjustable. Packaging was minimal. Quality of the material and seams appeared to be as good as other good quality dry bags. ... show more
