This seemed at first sight well designed, it is manufactured in Britain, and overall seemed serious. I used to surf a while, but after a few dozen sessions, it was no longer watertight. I highly recommend. This is how you shoot electronic keys ... I said that it was difficult to find a good waterproof pocket, all the ones I have used rapidly took on water, including the Pak-Pak Denko (found today). I'm always looking for a good product.
