From one-lap dawn patrols to 10,000-foot days, the Black Diamond Ascension Nylon STS Skins offer standard-setting traction on the uphill with efficient glide thanks to our redesigned plush material, which is now 20% lighter and more packable than previous versions. The Ascension Nylon STS Skins feature our patented STS tail attachment system, which provides up to 10 cm of adjustability for using with different skis in your quiver or for easy tensioning. The adjustable tip loop accommodates a wide range of modern ski tip shapes. We also gave the skins a pre-trimmed, bikini-style tail for reduced drag and weight.
