I’d buy one just not in black. I live in Texas which is located approximately 3 miles from the sun for 7 months of the year. I need no more black t-shirts.
I live in TX too. I just wear my black shirts when I go from an air conditioned home to an air conditioned car, and from there to my air conditioned office.
For real though, I put it on black because it makes the Back to the Future font pop. Woot has future plans someday to offer a shirt choice, so keep it in mind for someday. Or for your future summer vacation to Alaska or something.
