The MPS or (same suit) cheaper on ebay will do the job very well. I have witness one that went down hard at the track and still in use. the rider was bruised and sore as with any suit, but walked away to ride again.
Good leather is good leather. Stitching and padding
will make the difference when sliding down the track. hit the wall and no suit will save you from broken bones or worst. Bates ain't that big in the road racers world and they fall 10X more than we do.
I've had 2 suits over 10 years (40 lbs) and i'm ready for the 3rd because I outgrew them. Do you think i should buy a $1000 set of leather?
