The padded non-stretch design uses high-tech memory foam to cushion your neck and shoulders. The memory foam conforms to the shape of your neck so as to avoid any uncomfortable pressure points. For example, having a button on the back of your shirt or the clasp of a necklace pushed into your neck by an unforgiving strap. 2.5 inches wide (6,4 cm). Antimicrobial and wicks away moisture. Fits a range of instruments including saxophone, clarinet, English horn, bassoon and oboe.
