What makes this tee Transcendent? Transcends temperature: one side is French Terry Fleece to keep you warm in cooler temps. Flip it the other way and it is like wearing air in warmer weather. We estimate a 15-20 degree temp swing. Transcends clothing: our super nature TreeSilk™ fibers connect you to self, and it's made of nature & replenishes nature with one tree planted for every tee sold. Transcends occasions: the nicest dress shirt you’ll want to sleep in and the most luxuriously plush sleep shirt you’ll want to dress up in. Our relentless devotion to design is crafted to flatter every aspect of the human form: a length to elongate the torso, a uniquely hand-cut neck line, arm hugging sleeves to roll up or down, and raw edges everywhere, just like life. Each tee plants a tree. You are transcendent.
