The YAC 1430P Air Cell Neck Strap uses their patented Air Cell technology. By trapping air with specialized materials that offer flexibility and cushion, Air Cell strap technology delivers maximum comfort for lasting performance. It features slip-resistant air-cushions and a rubber-covered hook that prevents scratching of the instrument. The YAC 1430P neck strap is extra wide and ergonomically curved for comfortable use with heavier instruments like the baritone saxophone and bass clarinet.
