Stealth® originally set out to develop a rubber that would actually improve climbing by increasing the amount of body weight rubber could bear before its bond broke away from steep rock faces. After several years of research and experimentation, Stealth® rubber was born. Stealth's® unparalleled success in the climbing world made other athletes take note. The demand for other Stealth® sport applications was so high that Charles Cole returned to the lab to develop additional sport-specific formulas. The development of a new formula involves years of field-testing, with some of the worlds' best athletes using these sport-specific compounds in applications from water and snow to rock and trail. Each of the rubbers in the Stealth® family is specially formulated to excel in specific conditions, but they all share Stealth's® unique blend of high friction and shock absorption. The difference between Stealth® and other brands on the market is obvious. Quite simply, Stealth® provides the best friction on earth.
