I started looking around for shirts and the main thing I got from this exercise is I have way too many t-shirts!
Here are a few but I know I attended more PSPs than this sample. I'll find them some day.
There are so many that I would love to have back. This one comes to mind first every time I hear this question.
Custom ordered H-530/555 with a very custom finish.
Ren is playing it in this video right before I got it.
