I love the Flight Crew Mens shirt. It is very comfortable, stylish, and durable! The quality is very good. For sizing I am 6’2 and weigh between 235-245 as I fluctuate from summer to winter. XXL fits well especially when I am 235-240. I don’t have that much of a belly, maybe that will help for finding your correct size. I have several Alp & Rock products as does my wife and we have never been disappointed in any of them. They tend to be our go to clothing if we are going out anywhere. All of the items I would rate 5 star as we both have well over a dozen items of clothing. For my wife Alp & Rock is my favorite Christmas store for her every year. I hope Alp & Rock continues to maintain their high quality & fashion!!
