Canterbury clothing uses the term XB in its sizing rather than XL. XB is simply a slightly wider fit than XL and known as a ‘relaxed' fit. So if you are normally a 2XL in other brands you are probably an XB in Canterbury, or if you are normally a 3XL in other brands you are probably a 2XB in Canterbury. The CCC size range goes from XB to 7XB (chest sizes 120-156cm, waist sizes 107-137cm). Please check the size chart for each product before you order.
