Use an S-Power sling with your sling gun. They provide unparalleled progressive thrust and retain their power better over time. Latex material and a special production process ensure the slings retain their elasticity up to the breaking point. They are machine elongation tested, ensuring each one arrives at its splitting or drying stage three to four times slower under equal usage conditions. These latex slings have a conical ring, which prevents the parachute effect and increases performance.Materials: LatexDiameter: 19mm.Warranty: Two year limited
