Vector Kiteboarding Pro Short lines are made of 475kg Dyneema® kitelines, designed to become the best universal kitelines on the market. Dyneema® fibres are up to 15x times stronger than quality steel and up to 40% stronger than aramid fibres, both on weight for weight basis. Dyneema® is very lightweight and floats on water. Vector kitelines are PU coated and therefore resistant to moisture, UV light and chemicals. All in all it is the strongest fibre in the world and extremely durable to deal with the often harsh conditions kitelines get to endure. It also makes them perfect for those megaloops!The Vector kiteboarding Pro Short lines come in sets of 4x lines to ensure that all 4 lines have the same stretch, length and quality to ensure safety. Compatible with all brands that use a standard setup with 4x equal lines. Grab a short line length to boost your loop speed of your kite or increase your current line lengths to extend your wind window in lightwinds. Simply mix and match to feel the difference. Sizes: 3m, 5m, 12m, 18m, 20m, 22m and 24m Knot / Loop Connector Sets: Kite brands vary in how they attach the kite's bridle to the kitelines, using either knots or loops. Therefore, Vector offer two pigtails with loops on both sides (red and blue lines), and two lines with a knot on one side and a loop on the other (grey lines). To ensure that you can still distinguish the left grey line, it is marked with red. **Knot / Loop Connector set sold separately.**
