Black Diamond Ascension GlideLite Nylon STS Skins cut weight and bulk from your backcountry load. Skinnier than a regular skin, the GlideLite has a Tractor-Print base which allows them to be folded even smaller, so you can easily stash them in your pocket at the end of a climb. The STS attachment system fits any tails out there, including twin-tips, and the reversible double-bar tip can be attached to a much wider variety of skis than ever before. The GlideLite Nylon STS Skins need to be on your skis or in your pocket for your next lightweight backcountry tour. Bottom Line: Reduce weight, not performance.
