The 100% polyester Transformers Autobot Tonal Glow 59Fifty Cap glows in the dark...which makes me wonder if this great hat from New Era is actually a Robot in Disguise! That's the only way things can glow in the dark, right? RIGHT? Great for showing off your style and your love for the Autobots, the Transformers Autobot Tonal Glow 59Fifty Cap has a sublimated flatbill and all of the white components of this hat glow...though I don't know how you would have gotten that impression earlier.
