Black Diamond skins are efficient, trouble-free and easy to use. This year we’ve made things even simpler by offering pre-trimmed Ascension Skins, fitted to a range of Black Diamond (and similar shaped) skis. We’ve also adjusted skin sizes to cover a better range of ski shapes and added an extra large 130-mm size for gargantuan skis. This builds on other improvements, including the fortification of our legendary glue, refined fiber length for a balanced glide/climb ratio and an additional hydrophobic treatment to prevent water retention.
