What exactly is ‘Kepur’? This is the material you use in your guitar straps.

Kepur (pronounced, "keeper") is our indestructible strap. It is made with a special polyurethane material that we call, "Kepurthane" that has a web enforced inner core, but the exterior is completely smooth. The material, originally manufactured for emergency vehicles and military applications, is so strong that we actually had one artist use it for pulling their van out of the mud while they were on tour.
