The Lock-It LIS 002 P2- RED Guitar Strap Red is made of propylene. This is a high quality plastic. It is a very sturdy and durable material. So with the purchase of this guitar strap you have a purchase for a very long period.
Where most guitar straps become loose around the mounting buttons after a certain period of time, the Lock-It system has found something new. Namely the eponymous lock-it system. This is a system that has an extra lock apart from the normal mounting.
This lock consists of a slide that presses against the guitar's confirmation button. This is enclosed in a leather housing. As a result, the system is not visible and you just have a nice guitar strap around your neck.
