You ridin a Harley? jp. Yeah that should be fine. Race leathers are around 1.5mm I believe. CE armor is nice but it could use more. Another thing is I haven't had good luck at all with motorcycle-superstore.com and I won't personally ever buy from them again.
not a bad looking jacket my only concern is their isn't any ventilation and for that price you can get some really nice Icon, Aplinestar, or Teknic leather jackets. I would keep looking for something better but its your jacket not mine. Buy what you like.
