This is what you do buddy. Go onto the saga website then go to shop. there's a link that says sizing then you find what you want to buy. Then it will tell you how long the item is in either in or cm. then you go to your mommy and ask for her tape measure and you go from the top of your shoulder area down to where you would like the bottom of you jacket to end and you find the closest size in a S,M,L,XL,XXL. BOOM There you go young lad
