Great jacket at the best price I could find anywhere. Style is great and he material seems strong and well made. I've seen more protective type jackets but this seems good for my speeds. Can't really rate the protection fully but will update if god forbid I go down. This jacket cover my lower back nicely and my longer arms are covered to the wrist. I have a small frame and wish the size small arms were on the xsmall jacket and I'd probably end up in that size. But maybe when I upgrade the back protector it will be a bit snugger. Enough room to wear a hoodie under during cooler rides. I'm in the Bay Area so most days with the sun out I wouldn't need a hoodie under but fall evening and winter it'll be glad it has he room for it. Keep in mind for sizing in 5'5" 117 pounds 32b.
