i cant see them working. a duck dive, or good fall would flush it and get all that stuff soaked. plus the price is insane
they keep you dry, but they don't insulate well unless your wearing stuff under them, making them quite awkward for surfing... not to mention if you get a tear you are probably going to fill up with water, sink, or die, or any combination of those things.
I used a dry suit many years ago. Unlike this one, I didn't wear anything underneath. It did leak a little bit, but even on the coldest days I was cooking inside.
The water that fills up the drysuit has an equal bouyant force to the water outside of the suit. So it wouldn't cause you to sink, just get cold. i'd like to try one, but a good 5 mil works just fine.
