Button fell off when unbuttoning on first wear, but I’m a large guy and I’m aware that most of this clothing isn’t made for heavier people! A little tight on the shoulder but now that I’ve glued the button back on I wear it a lot, I just don’t close it up! I have the 4XL. The shell doesn’t really feel like cotton but it can stand up to a UK Autumn and I’ve even been wearing it in Winter. Very well priced, would recommend!
