The 2'' Cotton Series Guitar Strap from Lock-It feature 100% cotton fibers with a built-in snap-action lock to prevent the instrument from becoming unfastened. It can be used by musicians wanting a softer feel, more comfort, and less shoulder slip than a poly strap. The guitar strap is adjustable from 36 to 60'' and can be used with a built-in thumb-back button, which securely attaches it over the guitar's end-pin and locks the strap securely in place. Colour: Navy/Black.
