Neotech Soft Sax Strap Red Junior, with Swivel hook.

The innovative design incorporates neoprene with a control-stretch backing. This combination allows the weight of your instrument to be evenly distributed over a larger area on your neck and shoulders while absorbing the shock of your movements. This is how the strap makes your instrument feel 50% lighter. Fits most saxophones. Easy to attach with a choice of hooks: swivel hook or plastic coated metal hook. Very strong and durable. Fully adjustable. 

Size approx 15"-19" (38.1-48.3cm) back of neck to end of hook
