Do you know it rips easily, or are you speculating because it feels thin?  I thought the same thing, but I bought a pair of over the top pants, and they haven't cut at all after about a week of skiing in them.  Before that I had burton pants, and they got cut to shit the first day I skied in them, and still do every time I go out with them.  My buddy had some HH pants, and the same thing happened.  Oakley' s made the best pants I've owned so far.  The material seems thin, but its held up better then anything else I've had.
