Well for the home shirt my fat bastard self normally gets an L but had to move up to XL as the L was far too tight, it felt like an M. XL kind of feels baggy but at least I can get it on, could barely get L over my head. 3rd shirt was a perfect fit, I’m sure they’ve used the same material on the replica as they have the pro, it feels so light but easily gets little clicks and bobbles on it because of the material.
