Its funny that you should ask that, because I just had this sample sitting on my desk right beside me. It was printed while I was in New Jersey with Bob McCormack. We printed this particular sweatshirt on his 932NDS a few months ago, and I have worn and washed it countless times since then.
We have also printed on plenty of other colors as well, and even across the front of a pocket or zipped hoodie.
