The Prolimit Vapor hardback harness is the most technically advanced harness in our range, It is designed for maximum support and comfort during fully powered-up riding. The moulded hardback handles the high kite loads we looked for the perfect material to use in this load bearing part. We found a unique, patented material, called PURE®, that was developed in the Netherlands and is ideal for watersports applications.PURE® is a patented 100% polypropylene material, which is fully recyclable. The extruded strands are woven and heat fused in a mold to form a matrix that offers excellent strength and stiffness. Containing no carbon it is friendly to the body and the environment. The material is 100% recyclable and is solvent resistant and stable. PURE® material has a high stiffness and low density (0.78 g/cm3; for comparison: Water is approx. 0,99 g/cm3) Therefore lighter than water and the PURE® material floats.
