The mailman dropped off my package today. Based on the chart, I ordered the 6X in the long sleeved version and I'm glad I did. Depending on the manufacturer, I usually wear a 4X and sometimes 5X but I wanted to be safe on this special order deal. I'm 6'4" and 360 pounds and I think this is the right size jersey for me. Thanks PJ and Jonny for all of your efforts. This is my first cycling jersey and I love it!
