HEETA Dry Bag Waterproof for Women Men, Roll Top Lightweight Dry Storage Bag Backpack with Phone Case for Travel Swimming Boating Kayaking Paddle Board Camping Beach Accessories (Navy Blue, 5L)

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.

The bag itself is pretty decent at keeping water out if the bag is folded correctly before closing. I used this during a day trip at El Yunque in Puerto Rico recently. I was jumping in the river and water pools all day and the bag was submerged for a long time. It did let in a little water in but I suspect I didn’t close it correctly and considering how much water it was under, I think it still did a decent job at protecting items inside. The phone cover that comes with the bag on the other hand is absolute perfection! It kept my phone bone dry the whole time I was in and out of the river- actively swimming in the river mind you. I used it for an additional three days and it still is like new- not fallen apart as some of the other reviews say. All in all I’m pretty happy with these!

We took this dry-bag on a Caribbean beach holiday and found it worked especially well for the days we spent kayaking. The straps made it easy to carry and also easy to clip to the various cleats and straps on the kayak. It was quick to open to fish out cameras. The mini bag could take two phones out of their cases, or a phone and a small pocket camera, plus a couple of dollars or credit card. For us, it was somewhat less successful on the beach because the grippy nature of the neoprene (?) just seemed a sand magnet. But maybe we were just less cautious about opening it on sand than we were about water. Good buy, very useful, glad we brought it.

Bought it to go to a Waterpark. And it did the job. It held everything I needed safe & dry. I had diapers, wipes, a bottle, my wallet & my phone in it. Easy to use as well.

I don't know how waterproof these bags are but they have a stander waterproof closure and the 5l size is perfect for clipping to a backpack to add extra space for food. The 5l is pretty close to the size of a US plastic grocery bag.
