Nobody can deny that when it comes to hats, Jay is the man with style. Over the past few years Jay has been wearing a "spiky" piece of headgear (anyone got a better description), which has recently changed from solid steel (and very heavy) to be a more manageable carbon fibre version.
Well, Jay's headgear is made by a company called Accord Case, who are primarily in the business of making lightweight musical instrument cases, but as part of their research and development they've been creating headgear for Jay.
At the AccordCase.com website in the gallery section you'll find some great pictures of how the hats are made.
If these hats are a little extravagant for you, then don't forget that the more traditional hats are made by Rod Keenan in New York.
