A good quality fabric suit is breathable and abrasion resistant. Go back 40 years ago and there were leather suits. Not anymore. Don’t see any F1, IMSA, INDY drivers with a leather suit. You can purchase a suit that is flame resistant; just don’t look at the price.
My son tried years ago to convince a motorcycle racing suit manufacturer to come out with a version of their suit for karters with pads for shoulder, knee and elbow protection. Fell on deaf ears because the market would not be profitable.
