Bag gets wet, too thin.

We use these at our restaurant for pizza deliveries. 7 pizza boxes fit inside, but being in there too long will make the bag sweat. This is no problem as long as the pizzas get delivered quickly. Bag also has no insulation, straps work well. Gets the job done for what we need.

once you fill the bag with water it doesn't leave much room but probably OK for a short run or hike. My biggest problem is the bit valve leaked from day one. I think I saw other reviews saying same thing

I use this after taking my dogs out in the woods and it seems to do the job but the liquid is way to thin. When I put it on my hands and try to rub it on the sides of my dog or their legs, the shampoo just runs off my hands since it's thin as water. The thickness of the shampoo needs to be improved.

Good bag when holding everything except water. I had to make sure the bottom of the water bag was sealed correctly otherwise it would leak all over the place. Also the zipper caps that u pull on to open the bag broke. It is very frustrating opening my bag now

When it rains, water will filter through this product. Not as thick as the one I had before.

We bought this to make a trek from PA to AZ.  I wanted a waterproof carrier since there would be a good chance of some weather hitting us, well, it did and this bag FAILED!  We literally had a puddle of water in the carrier after the first day.  I don't know if we had a defective bag or if there are significant design flaws, but the zipper flap folds up so all the water can get in.  It was so bad we had to ship everything we had in the carrier from St. Louis to AZ.  Needless to say this is going back to Amazon (which BTW were great about the return).

For the water park, we put the bag into a cheap string drawn backpack.  My wife or I wear it while we are with the kids in the kiddie pool. Phone, keys, wallet all go in. It was submerged and we had no problems.

Immediately after getting the backpack, I put two dry towels into the bag, sealed it up according to the instructions, and put it in the pool to float around for a couple hours. It was never dunked, and the top of the bag was above water for the whole time.  When I pulled the bag out and opened it up, one of the towels was soaked and the other damp.  Probably fine for hiking through a rainshower, but I wouldn't count on it keeping water out if it takes a fall I to the ocean for long.  I intend to only put waterproof items (or items in REAL waterproof enclosures) in the backpack, otherwise I would return it immediately.

Disappointing, and definitely not what the videos on their website imply.

Used for a couple weeks, then the phone got soaked for hours in water and shorted by this cup of water spilling in the midst of the night. Rice bag didn't work. Not waterproof! Seemed ok before hand, though.

This is a nice idea, and when I first used it I was quite happy with it.  I read either in the description or the comments that it also was useful as a dry bag - to keep items dry.  I used it as a dry bag to carry items when I was walking through the Baths at Virgin Gorda.  But the next time I tired to use it as a wash bag, it leaked out of the base.  Perhaps I had allowed it to sit on the floor of the boat or the bus which transported me to the Baths?  I certainly wasn't aware of allowing it to rub around and get damaged.  I may be able to reseal it with waterproofing, and I can use it in the sink or in an other bag, but that limits it's use . . . I wish it had the same heavier coating over the end of the bag as it has on the underside of the bag.  For the cost, I think it could be a better item.

Bag is OK....though not waterproof!  First time I rode in the rain it got soaked along with the contents.  Would not recommend this bag for all weather use.

Good bag, but it will get wet heavy rain. Sadly, it doesn't come with rain cover like new line of DNA bags.

It's a nice roomie bag, plenty of room for keys, phone, etc. it's also nice that there's a full size water bottle however when running it leaks everywhere! And the bouncing of this bag is out of control!

I kept the bag, but it totally leaked. Luckily I tested it. Ill probably use it in scenarios where Im in a boat and it could get splashed on, but in general....not impressed at all.

I like the bag but the liners are way too thin. I rip them just trying to put them in. The simplehuman code b liners fit perfectly and have a drawstring so that is what I use.

My daughter loved this backpack when she got it for Christmas. The weather finally warmed up and she took it to the lake to kayak. She got back to shore got the backpack to put her shorts on and they were wet! A tiny amount of water from the paddle was in the kayak and it went through the pack. Description says water resistant but apparently it isn't. Looks like if it rained the insides would be soaked. Other than that a nice little pack but she wanted it to kayak and we are passed the return window so this one will go in the closet and we will look for another one.

Failed the paper towel test! Maybe mine were just defective, but you definitely should test it out before doing it.  Both the fanny pack and dry bag were filled with water.
