I have taken this camping with me. I put my all of my camera equipment in this. We went for a hike. It was in the summer and had a flash thunderstorm. I had my cameras with me. But the case was out in the open locked shut and not a drop of water got in. So I started wondering if this case does what it says it does. I took it to the stream nearby, took my equipment out and dunked it in the water closed. Not leaks what so ever. Wonderful product kept my most valued possessions safe.
