Seal skins are an essential element for cross-country skiing and Nordic skiing. It designates the fabric glued to the sole of the ski so that it slides only in one direction, to facilitate the ascent of the slope. These seal skins are effective for clinging to the snow on the climb. They can be made of mohair, synthetic or hybrid with conventional gluing or silicone coating. When buying a seal skin for cross-country skiing, you must pay attention to the material but also to the type of binding, with or without glue, and the type of attachment for the front and the back of the ski. It is easy to use and cleans quickly.
