    Greatly undersized. Recommend ordering two sizes up. My 2X is a medium at most.

    My XXLT tops are much smaller than the Henley in same XXLT size. Otherwise, another stellar Key product.

    Runs very small

    Posted by Jesse Jones on Nov 17th 2021

    This shirt runs very small, which is surprising compared to other shirts I have purchased from Key Apparel. I would say that these shirts run two sizes small. I usually where a Large Tall and that is a little too long. I tried a Large in this shirt and it fit like a medium. I re order an XL and that was too small as well. I don't know if I will bother trying a 2XL, because you have to pay postage on returns.

    Well made. Heavy enough. Tight, though. Consider buying a size larger.
