Thanks for the answer below ALW. Well I asked the questions for nothing. Today I was acutally able to check one out at a shop I hadn't visitted yet. The back of the board is a 400 or 420 Denier nylon I believe, since this a non-wear/non-impact area that is ok. But I did notice that the sides of the board, and the nose of the blocker is all clarino. Plus there is clarino in other areas. Awesome blocker from looking it over and putting it on... But I will put in my own review in the future if I get one.
*One of my Christmas presents is going to be a blocker. Which one from my list is up to my guesswork
