This is the "waterproof" fly box I've had leak on me several times. I think it may be a little warped and just not sealing even across the oring.
I tend to wade a lot thru chest deep water at times to get to the other side of the river or have stepped off a shelf into too deep of water when smallie fishing.
I carry a couple of fly boxes with poppers and streamers and they often get dunked in the chest pack I wear. I would really like to get a recycled waders "nook" but they are not seam sealed around the stiching.and I like the fact they are recycling a product to provide more enjoyment for us anglers.
Guess I will continue to just stick what I'm using now down into the top of my waders for now. thanks for the comments.
