The singer had been wearing it onstage. The theft occurred during a 30-minute window between the beginning of the encore and the end of the show.

The hat was bought at a truck stop while on tour many years ago. It is made of brushed, soft cloth, although it is hard and maintains its shape. Kilmister had personalized it with his own original decorations and designs.

The hat has become Kilmister’s trademark. He always wears it when performing and has been often photographed with it.

A reward is being offered for the hat’s return. Individuals who have information about its whereabouts can check out for contact information.

Motorhead have been touring in support of their Hammered album.
