Nice but Sizing Runs Small

Nice shirt, I normally wear a mens medium but on the larger end of the spectrum. I ordered a M per the sizing chart and could not even button the shirt at the chest. I ended up giving the shirt to my son and ordered the large. I anticipate this will fit.

Nice Enough Shirt

I always wear a size Lg, but this shirt was so small in size Lg that it was unwearable and had to be returned. The online product description should note that Columbia clothing tends to be small--apparently everyone knows this but me. However, I liked it enough that I bought another one in XL and it fits just fine.
