Apparently its up to whomever is in charge of our account with zazzle to add in the appropriate grey microfiber tech shirts..
Here is my question and their response...
question:
Several of us would like to purchase a performance microfiber kind of shirt but all you have available is white. We would rather not have to go to another vendor and re-design this thing so the easiest thing to do is to ask about product options. Specifically would like something in grey or maybe a light tan. We use these shirts a lot and they are a kind of uniform for us. We do a lot of down on the ground kind of work and usually get kindof dirty as a result. White won't cut it and some of the members in hotter climate (AZ, Florida, etc) would like some other options. Thanks in advance!
