I got two of these shirts for archaeology field school and they are doing great; provide sun protection and aren’t too warm/stuffy out in the Florida sun and heat. Dry pretty quickly. I did size down to a Small when I’m usually a Medium; I’m 5’7” and 135lb and the Small is comfortably loose. The Medium was too billowy. Bonus—I found I can tie it like a sarong and get good coverage too in a pinch!
I ordered the light khaki, but in reality it was like a light yellow. I personally don't have a problem with that, I love funky colors but if you want to stay close to the true khaki, this color isn't it. I bought it for a charter boat fishing day and it did the trick. Great shirt for a good price, cheaper than the popular name brands.
