“Im 6 feet 250 lbs with a gut. I bought the XXXL big guy jacket to wear on really cold / windy days where I can wear layers and not feel restricted. The XXXL is larger all around BUT I plan to wear it with the following tee shirt , Under armour and a hoodie. Wearing these items under a XXL with my gut was tight. With the XXXL the fit was fine. Once you get the fit right the jacket and or the Hoodie are really good. It keeps you really warm knocks the wind down and not restricting while moving. Jacket wears really good as well , washing machine no problem tough stains a little shout or stain remover works. Aside from everything I mentioned it is DWR which makes the jacket water repellent.”
