HEETA Dry Bag Waterproof for Women Men, 5L/10L/20L/30L/40L Roll Top Lightweight Dry Storage Bag Backpack with Phone Case for Travel, Swimming, Boating, Kayaking, Camping & Beach, 11 Transparent Colors

I used this for camping in my car. I don't want a refrigerator unit to worry about, so I use a soft insulated leak proof cooler (Rockbros from amazon) that fits behind my passenger's seat. The cooler does not leak, but the melting ice water in the cooler gets into my food. So I bought this. It worked great. I actually put all of my cold food stuffs into the bag and then put ice all around it. I could fit a quart of milk, a small box of lettuce, some hummus, cheese, and salad veggies, chocolate bars, inside no problem. The food stayed very cold, and no water got in IF I kept the bag upright in the cooler. If I laid the bag on its side, it did allow water in. . . Even with multiple folds at the top. Once I figured that out, it was perfect.

This was a great purchase. I was able to leave my phone charger, wallet, etc. with me in this bag while I went bamboo rafting, speedboat rides, and even in the ocean on the beach, I also took the waterproof phone case underwater with me as I was scuba diving, and my phone was perfectly fine. Great purchase. The bag also holds quite a bit of things if it is really hot outside it might get a tad bit steamy, but nothing terrible to the point. It might mess up any electronics that you had because I also kept my portable charger in there.

We've taken this out on lakes many times and it works well. Nice thick material. It has a good leash to attach it to the kayak ropes. I recommended one to a friend who just bought a kayak. You can blow it full of air before you roll it up, and it will float.

The bags themselves (bought a 5L and a 10L) seem to be well made and effective. Would have given 5 stars but for the too-short cross body strap, it needs to be much longer.

Great waterproof bag. The exact size and color I wanted. It is semi see through. So if you don't want anyone to see what you have, then this may not work for you.

Got for cruise excursion; worked like a charm! definitely will use on boats and other water experiences! got numerous compliments, too!

I got the 40 liter and it is huge. I like the double straps so you can wear it like a backpack.

I took this bag to the beach for 12 straight days. I took a couple of light weight towels and lots of other stuff. It was big enough for me. During afternoon rain storms everything in the bag stayed dry. Very nice. I have the 20l.
