Never lose a throw weight again. Notchs proprietary throw weight design stands out against any background - leaves, sky, dirt, you name it. The weights are color coded according to size, and each 1-features 2-panels of the high contrast pattern that's not found anywhere in nature. Made from genuine 1,000 denier Cordura material with extra stitching and a welded ring, Notch Throw Weights are tough enough to hold up to anything you can throw them at.
