The Dakine Slayer Pro knee pad is a low-profile, high-performance pad that is designed to protect your knees without getting in your way. The CE certified DK Impact padding is soft and easy to move around in until the moment of impact when it becomes rigid. A single upper elastic strap lets you dial in the fit, and a seamless calf band ensures a comfortable fit. It is fitted with a tough Cordura shell, and features Polygiene Odor Control technology to keep things fresh. The shell is also ergonomically designed in a pre-curve shape to make it more comfortable to ride in, and features silicon grippers on the top and bottom to make sure it doesn't start to slip. DK Impact foam protection and comfort Lightweight and breathable sleeve for comfort Ergonomic designs allows easy movement Aramid ripstop for optimal durability Equipped With Polygiene Polygiene prevents the growth of odor-causing bacteria and fungi at the source, permanently. To do this, Polygiene uses low concentrations of silver salt (silver chloride), which has antimicrobial properties, to prevent bacteria and fungi from growing. This permanent treatment is applied at the finishing stages of textile production, and field and lab tests show a high level of odor control beyond the usual lifespan of a garment. Polygiene silver salt technology is only active on the textile itself, and there is no effect on the natural bacterial flora of the skin.
