Sheldon,
My first karting suit was a Sparco Imola. It lasted for 3 seasons before it wore out. The webbing under under the arms gave out after repeated washing and use. I also had the collar replaced after 2 years because it wore where it rubbed against my helmet/neck collar. My wife used Spray ‘n Wash to get grease stains out and that worked pretty well. The suit performed well in protecting me in a crash – no abrasions.
