I'm Gabriel Platt, creator of a black t-shirt that doesn't heat up under the sun, using nano technology AMA!
We are a hi-tech fashion startup from Germany which recently got notorious for creating the blackest shirt in existence.
Since all our clothes are black, we were often confronted with the unpleasantness of wearing black in the summer.
So we found this nano-coating called coldblack which manages to reflect the (invisible) heat rays, but swallow the visible light spectrum, turning it black. And made a T-Shirt from it.
Here is some more background info from an article in Dazed&Confused Magazine.
