The 5 series is the hardest wax in the HS line, and is a great choice in cold conditions, due to its great durability and dry friction properties. It's a great choice both for alpine and cross country. Despite being a wax for cold conditions, the melting point makes it easier to apply than many competitors in this area, without sacrificing the great glide properties. For fresh, old or manmade snow. When ironing, take approx. 8-10 sec. to cover your ski base. The wax can be re-heated after cooling to room temperature (10 min) for better durability. Scraping after approx. one minute. Im
