Some of the enemies of natural, organic latex are sun rays, heat, and ozone pollution. Ultra Violet Rays (UV) can quickly dry out, rot the bands, and make them brittle. View Trumark's test here. It's not a good idea to leave your slingshot inside a car, which can get especially hot. Just as it doesn't take very long to get a severe skin burn, latex is also sun sensitive, and can be damaged in a similar way!
