Neotech case packer is the perfect solution for carrying larger instrument cases or other gear safely and comfortably. This set of two straps is incredibly versatile. A single strap can be used for carrying a case over one shoulder. Both straps can be used together for a backpack-style configuration. The straps fasten securely to an instrument Case's D-rings or other connection points with a sturdy 1" (2, 54 cm) wide nylon webbing. The length of each strap can be freely adjusted 24"‐ 54" (61cm– 137, 2cm). The neoprene pad with our patented internal control-stretch system is easy on the shoulders and can actually make your gear feel up to 50% lighter!.
