thought about this and it is a mixed bag. some would like them, others want cotton. It also comes down to cost, and depends on the printing method used, with performance shirts generally using sublimation. I can look more into it on Monday, but it may be for future shirts.
Update for you guys. These are "in production" but there was a delay with the screen printer due to the wuhan virus within the company. The job has been pushed back as they try to catch up with orders received prior to mine.
My guess is it will be in two weeks, before Christmas, or right after the new year.
