This hat is made from a lovely black oiltan and hand-stitched with a flourescent green thread. The mohawk spikes were hand painted with a neon green. This hat will glow under a black light. 
 
Built into the earcaps are headphones. It's a 40-mm precision Headamame headphone kit that I modified to fit. They sound AMAZING! You do feel like you're in your own little world. This includes a removable 3.5mm audio cord for the headphones, as well as an auxiliary to USB-C adapter.
 
The hat will fit a size Large to Extra Large, or down to a medium if you have a significant amount of hair.
