I was lookin' through sportstuff's web page, specifically at the new tubes that you can steer and stuff for another thread else where and then one of the videos had this guy wearing what looked like a football uniform top, pads and all! It does not look like they are selling the thing yet, so this is the best pic i could find.
now that is an IMPACT vest if i ever saw one
Sports stuff always seems to go above and beyond (sometimes to the point of lawsuits as with the kite-tube)to make tubing look incredibly EXTREME.
the vest would probably be too restricting for wakeboarding eh? that support in the back might help the neck on some wild crashes?
