It fits really well, I am 179cm tall and relatively skinny. The M-size is a bit loose on the chest but that is a good thing. I am astonished by quality of the fabric and stitching.
Nice quality item. The MCBK is very close to the original, see the FlexFit cap on the photo for comparison. Stitches are good, material is fine. Sizing is a bit off - I’ve ordered XXL pants, which fits perfectly, yet the XL shirt is big for me.
