Our unique latex formulation and dip manufacturing process delivers radical modulus strength. The power curve increases as bands are stretched for optimum performance. Special anti-oxidants help protect against harmful U.V. rays, prolonging sling life. Wishbones are made of durable Spectra cord and provide superior strength, durability and silent operation. 300 Elite series bands are the standard sling for all Elite and Mid Handle models. They feature a 5/8" outer diameter and pack more punch than the standard 9/16" bands.
