I really like these polos. I was given one with my company logo, and really liked it. Unfortunately, now I have a strong dislike for that company, so I had to donate it, and order a couple plain ones from Amazon.I usually wear Large (and sometimes XL) t-shirts, but I was swimming in the Large version of this shirt. I'm a 6-1, 210 pound guy, and the Medium fits me perfect. The polo looks great untucked because it is the perfect length and does not have that annoying bell shape that makes you look 40 pounds overweight. All 3 of these polos I have owned have fit the same, so it is good to see they are consistent.These are great polos to wear at my engineering office. You should probably wear something a bit nicer when going out, but are great for their purpose.
