Half inch wide strap with adjustable with quick release buckle.The Leg Strap is for Postion 4, and is used around the thigh. This position is good if you are not wearing a belt or pants with a belt loop, and want to transfer the weight of the uke away from the upper body. It also interferes less with untucked shirts than Position 3 (belt loop). It is more awkward if you plan to move your legs around though, so it is best when standing still or sitting. Small = 23 inches, Medium= 27 inches, Large =32 inches. Other sizes and colors available on request.
