This should have been included with the PUMA Offshore Jacket post, but I had already pushed publish before I came across this video.
Apparently, the PUMA Ocean Racing team keeps a YouTube account with videos of their adventures, and one of them shows the team fooling around and testing their [PUMA] gear. The team really put their stuff to the test, especially as they made 100% sure that their gear was as waterproof as possible.
If you can jump into water with your gear on and still come out relatively dry, I’d say your gear is pretty darn good. Watch the video for a demonstration.
