The medium size (5ft 10in, 165lbs) usually works well for me, but based on other reviews I bought the small size. , buy less. The shirt has a nice pattern on the inside and the material feels much nicer than the price suggests. Great shirt for work unless you are a skydiving instructor, or for a typical day in the city unless your city is in Greenland. In this case I would recommend the sleeves.
