    Keep your documents and electronics dry for sure! Super fast shipping! I had a bag like this that i had bough 20 years ago and it was awesome but it was also expensive back then. Imagine my delight when i only paid $26 bucks for a bag that Idon't have to worry whatsoever that my documents or electronics will get wet. This is not only waterproof bag but a dry bag that will positively keep your goods dry in any weather!

    I'm so glad I finally purchased this Aqua-Quest Mariner waterproof backpack I'd ... I'm so glad I finally purchased this Aqua-Quest Mariner waterproof backpack I'd been eyeing. It has already been to Yosemite National Park camping and also has kayaked its way to the Mokulua islands off Kailua Beach on the island of O'ahu. It's soft, light-weight, the perfect size, easy to clean, air-tight and keeps all of my belongings safe and dry. I'm so happy with this purchase and highly recommend it!

    Perfect for cruise excursions We needed a waterproof backpack for a recent cruise excursions to Stingray City in Grand Cayman via wave runner. This backpack fit perfectly in the front compartment and kept our towels and personal items completely dry.

    Great Waterproof Bag!!! I took this bag to jamaica and it was great. The bag is easy to operate (sealing and closing) and it stores a lot. We had two quick dry beach towels, books, food, wallet, and a few more items and it only filled the bag halfway. WARNING: If the bag is in direct sunlight, it does get awfully hot inside the bag. This was at the beach while sitting on the sand. We left ours open so that it would get some airflow. But you might want to be protective of any cell phones or iPods inside of it.

    New Favorite Bag! I ordered this bag to use as a backpack for a long trip where I would be taking my expensive camera into woods/wetlands were the weather was unpredictable, and also to use on camping trips in woods where bears were living (to use as a bear bag for my food and wrapped garbage). As a backpack, the bag was amazing. I had a 3L camelbak, my large camera plus two lenses in a padded camera pouch, food, wallet, etc. and I had so much room left over. The straps are padded and comfortable - I'm 5'7" and the pack fits me well. The straps are adjustable and removable. I can't speak to the waterproofness of the bag, as it didn't actually rain and I didn't drop the pack into water, but it appears extremely well made with nicely sealed seams. I have yet to use this as my bear bag when camping, but I'm excited to try it out. Love this bag!

    Best bang for the buck! For the money you can't go wrong! Compared to the junk they sell in wallyworld and the upper crust kayak and canoe shops this is the best. Bought it for canoeing and kayaking and it has fit our needs perfectly. We didn't want it for high mileage backpacking just keep our gear dry and allow us to carry our stuff to scenic spot for a riverside lunch, works perfect. One of our canoeing friends buys the high dollar items and found his $75 dry sack to be inferior to this affordable product. I am buying two more to use as adventure touring saddlebags on my Suzuki DR650, these bags are very comparable to ones costing 3 times as much and sold as saddlebags. Also considering another one to setup as a bugout bag. buy it, you will like it.

    Five Stars Very good dry bag! As a diver and instructor - I used this dry bag a lot. Keeping my dry stuff dry is a must. There's nothing worse than having to get into wet clothes which were dry. This dry bag is tough, great volume and keeps everything dry. Very happy with this dry bag.

    Great dry bag and good at what it is supposed to do. I bought this to use when we kayak and also when camping or going to the beach. It does a great job of keeping things clean and dry in all of the uses. The straps are handy to carry this on your back, and keep hands free for other purposes. This size is perfect for several beach towels and extra clothing, as well as numerous small items that we take on these types of trips, and it fits well into the bow of my boat. Great product.

    Strong and waterproof Took this bag on a 3 night motorcycle camping trip and carried much of my equipment (which is very light backpacking equipment) in it. Had some rain and the bag performed very well. I recommend it highly.

    Great Dry bag. We take these bags with us on our beach vacations. This is the 3rd bag we have bought and they are fantastic. We have even used them to float into the beach off the boat. Everything stays dry. The shipping on this was very fast and I would buy from this company again!
