Okay, the sonic fabric ties ties were a cool concept, but not so decorative. I'm totally on board with the recycled cassette tape fedoras, though. The sonic fabric seems like material better suited to hats than to ties. Not sure what happens if it gets wet, though...which is definitely something I'd want to know before buying a hat made from the stuff. They're not cheap (when do I ever post anything that is?), but, at $165, they're not obscene for handcrafted hats.
