Trumark's RR-2 powerbands are made from the best quality, pure latex-rubber.
A 0.4% carbon black jacket has been added to the rubber for the ultimate protection against damaging Ulraviolet light rays.
(Adding black carbon is a method proven to prevent premature aging of rubber which has been used in the tire industry for over 100 years!) The black carbon helps make them the most durable slingshot bands ever. All Trumark bands may also be conditioned even more against contaminating elements with 303 Aerospace Protectant. Conditioned bands have increased lifespan, and last many more shooting sessions with a minimum loss of shooting power.
