Neotech s accordion harnesses are comprised of two neoprene straps offering a patented internal control-stretch system for enhanced comfort and mobility. This unique weight reduction system effectively disperses the weight and absorbs the shock of your movements. The straps attach easily to the top of the accordion using 3/4 (19cm) webbing and at the bottom with convenient and secure Neo-Loops. Neotechas accordion harness series transform the accordion into a joy to play not a burden!The original Accordion Harness is ideal for small to medium sized accordions. The shoulder pads have a non-skid surface and measure approximately 16.5 (419cm) long and taper in width from 3 to 2 inches (76cm to 51cm). A unique back strap is also included in the original Accordion Harness which is adjustable from 4 a 14 (101a 356 cm).

The shoulder pads are 2.75 wide by 21 long (7cm wide x 533cm long).
