I recommend this tactical polo shirt if you are looking for something comfortable. This shirt has two shoulder pockets that can hold pens on each side or anything but the pens you want to put in the pockets. I definitely recommend it and I will be buying more in that capacity. This shirt is also made from a great material that won't snag.
