First off, this suit fits pretty tight. That's why I prefer skin suits, but if you're between sizes, definitely size up.
On my first ride with my new suit, I crashed, and incredibly the suit wasn't damaged at all, even though I slid on my thigh for a few feet. I got mild road rash underneath where my leg was covered, but my uncovered elbow got torn up significantly worse. If I ever have to end up replacing my road suit, I know I'm definitely buying another one from Black Bibs.
