From one-lap dawn patrols to 10,000-foot days, the Black Diamond Ascension Pre-Trimmed climbing skins for alpine touring skis offer standard-setting traction on the uphill with efficient glide thanks to its light and packable plush material. They are available in fixed lengths with pre-installed tip and tail attachments. Intuitive and easy to use, they feature an 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.
