Whoops, to the OP, since nobody has described the Ambrosio tape... It's vinyl covering a thin foam. A bit grainy, looks almost like leather, great grip, doesn't tear easily, just enough padding without getting bulky. Not sure about its grip in wet weather, though.

@bbm, any idea what the Ambrosio "yellow/black" or "white/pink" combos look like? I think I saw them sold at Ribbles but I wasn't sure of their appearance.
