No QC with this shirt, I order short sleeve and this long sleeve shirt 2XL works like Large, I read everything labeled 2XL but with mixed sizes, in the shoulders a little wide, and the chest and waist runs very tight, long sleeves, the arm is long enough to cover the wrist, but very wide, like the width of the bicep, I can't describe the incredible disproportion of this shirt. Another thing is that with this type of material, there is usually a slight expansion or strengthening of the chest and waist, this is not the case, it has a gray stench. this product.
