Like Mono cases, Mono straps are designed with indestructible materials, lightweight construction and smart features to contribute to the ultimate playing experience. A classic, minimalist design sporting hi-tech materials, the Betty brings the past into the future with a feel that must be worn to be believed. The Betty's wide wale design distributes the weight of heavy instruments. A thin memory-foam core reduces fatigue during long hours of play. Smooth and breathable, this material is used in wet suits. Get creative with the hidden mini pocket, which stashes picks, a slide, or whatever right where you need it for quick access during play.
