I knew ExOfficio is a premium brand with great products but did not like the sloppier look of their classic Air Strip shirt. I did order a number of different shirts and the Geo Trek'r is by far the nicest. light, comfortable, and with a nice touch finish for the material. I got it in white. Perfect fit for me and achieves the balance I wanted for urban and occasional more strenuous activities. I wanted something I can go to Italy with and sight see all day in but that also looks good in a nice restaurant. Does not back or side vents so not as "technical" as some of the other shirts but for my purposes of a more "urban" shirt, this fit the bill.
