Swix HS05 High Speed Wax Turquoise 900G (HS) series are great gliders for training and competition with very good glide properties. HS can be used as a race wax alone or as a base for top coats. 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.
