How to Properly Wear Chaps
Very Important: Chap length is not the same as your pants length. Chaps are sized by overall length. To calculate your overall length measure from your waist (where you would wear your belt) to the top of your foot or your instep.
The bottom of the chap leg should sit on top of your boot covering your laces. The proper length should allow the chap to be out of the way but offer you protection for your whole leg.
