This jacket fits true to size. im 6'2'' 203lbs and the XL fits perfect, room for a hood or sweater underneath, if you get a XXL expect it to float in the back when not zippered up because your body doesn't fill it out. The collar is amazing, full neck protection i doubt you would need a scarf while wearing this vest. This vest is really solid. Warm, durable, stylish, and very well crafted. I like pockets and this vest has alot of it. You cant go wrong with this vest.
