I (mistakenly?) read the description and found it to be 100% cotton, especially since Best Buy shows it in response to a search for "100% cotton polo" when it's actually 50% polyester ("ComfortSoft cotton") ) is. The fabric is scratchy and uncomfortable, and the drape of the fabric gives the shirt an ugly shape, at least for my body type. I'm going to give this shirt as a gift and buy a 100% pique cotton polo shirt because I bought it in stores and thought I'd buy it here.
