The only line specifically engineered for Kiteboarding applications. Q-Power utilizes an internal core consisting of linear strands of very high tenacity Spectra 2000® fiber encased in an extremely tight braided Spectra 2000® sheath. All strength in the line is attributed to the core only, with the over braid’s function limited to keeping the strand bundle together. Since the fibers are linear from the start, there is no continuous ‘stretch’ as found in traditional line, where the braid tightens with use. Any stretch is therefore limited to the elongation of the actual fibers, which is minimal when compared to braided line. Q-Power Pro is the most advanced kite line available. This 600 lb. test line is 20% thinner than standard Q-Line. Pro Line is treated with a special lubricant, which reduces friction when lines are twisted.
