I purchased a 2xl size according to size chart and it was still too small, material was polyester and itchy. I returned these. I was hoping for a nice lightweight high viz shirt. These were not it.

Nice color choices and price can't be beat. The description is a bit misleading as the fabric is a heavier polyester not unlike what folks wore in the '70s. Kind of warm for summer but fine for cooler fall/winter really. I have very cold office and my pits were sweating a little.

Very comfortable, with great colors to choose from. One of the reviews had mentioned it runs small so I ordered a large rather than my usual medium. I had to return them and order an extra large to have a relaxed fit. Once I did that it was great!
