Please measure the circumference of your chest using a cloth tape measure and add 1" if the measurement is an odd number to get to the next even number and choose your size from the chart below. Please note all measurements are in inches.
Comment: I like the look and feel of this jacket. Seems to have good protection also with leather in addition to armor in all the right places. Good venting too. Fits about right, I am 6'1" and 200#, and I got the XL, about the same size as other jackets I own. I would recommend this jacket.
