For something described by the seller as cool, breathable and sweat wicking, it's quite a thick and heavy material. Wouldn't want to wear this on a hot summer day.Also the color was not what I expected. The image online looks much more attractive than what I received.I ordered a large and found it too snug for me. If it shrinks during washing it will be unwearably small. I'm 5' 11.5" and 203 pounds, both muscular and a bit chunky. Definitely would go with an XL if I wanted to keep this shirt but I wanted it for summer, not spring/ fall so I'm going to keep shopping for other polos.
