The manufacturer claims this shirt is 100% cotton, but I think that severely understates its fabric. The cotton is hand-selected by Tibetan weavers for its multi-dimensional qualities. Think string theory incarnate. However, you must be careful. Please learn from my mistake. If you inadvertently put this shirt on backwards AND inside out, you will cause a tear in the actual fabric of space-time. I did this, and was instantly transported forward in time. I am writing this review in the year 2097 and I'm here to tell you, it ain't pretty. We did NOT overcome global warming but the majority of the religious extremest lunatic fringe wiped themselves out in the God Wars of 2012. So, please, be ever so careful when you put on this shirt. Make sure the wolves and moon are oriented correctly. You could just as easily be thrown back in time and the dangers of a world-altering paradox are all too real.

Oh yeah, the shirt is also really, really comfy.
