Well Mike sorry it has taken me so long to reply to this discussion. When sizing leather jackets you want to go for a jacket that can fit over a hoodie so that way when cold weather hits you can where the hoodie under the jacket and be warm. When it comes to chaps we here at Papa's size them around the thigh and size them to fit tight. Now it is up to you if you want them to fit tight or not you can always go one size bigger.
