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. The speed of the iron should be approx. 8-10 sec. on a skating ski. The wax can be re-heated after cooling to room temperature (10 min) for better durability. Scraping after approx. one minute. Important to have a good iron to get an efficient melting of the wax. HS5 can be used as a race wax alone or as a base for top coats. Recommended iron temp: 160°C (320°F)
