I travel a lot and cotton polos end up looking rumpled even after hanging in a closet overnight from the suitcase.  So, I went to find a substitute that can be considered business casual.  These fit the bill.  Yes there is a logo, but it is discrete and the sizing is correct per Columbia brand.  I have the yellow, red and turquoise. Only thing is beware, there is a back panel with vents.  You cannot really see this, it is covered, but if you did not have it, you would likely feel this shirt to be too warm.  Washes well and dries quickly.
