HS10 is a great base prep wax, but also a great training wax. Ideal in warm conditions, typically during spring skiing. For racing we recommend to go with a top coat as the final layer. The speed of the iron should be approx. 8-10 sec. on a skating or alpine ski. The wax can be re-heated after cooling to room temperature (10 min) for better durability. It's important to have a good iron to get an efficient melting of the wax. Recommended iron temp: 150°C (302°F).
