You need full leathers, back protector, motorcycle boots, motorcycle gloves and of course a motorcycle helmet. My question is what type of leathers must they be? Do they have to be a full race suit or can it be leather jacket and pants that zip together around the waist? For example, would an Alpinestar leather jacket and leather pants that zip together qualify or do you have to buy a specific two or one piece suit to be allowed? Does the back protector that is inside a jacket qualify or do you need a separate full length back protector? So would a leather jacket like this which zips into leather pants like this be allowed on the track at track days/race meets? The reason I ask is that I don't want a full two piece or one piece suit and like the flexibility of buying separate jacket and pants.
