The Sport Packs have an extra wide adjustable belt with huge dual elastic fasteners for optimal tight fit. Tough Nylon/Cordura fabric with heavy duty stitching. Extra wide back support made from soft fleece stops pods shaking around. Pod pouches equipped with drawstrings for easy access. Unused loops can be stored folded for minimum target area, therfore it is extremely variable for both front- and backplayers.
The Pro Toyz Sport Pack is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
