Here's what other sites are saying:
Sized specifically to fit the Pettitor Ski, the K2 Pettitor Climbing Skins clip into the tip and tail attachments on your Pettitor skis so you won't have to doink around with third-party skins that always fall off. These climbing skins are every bit as fast as the skins designed for some of the more backcountry-specific skis in K2's line and they grip like a tank tread when you're faced with a brutal ascent. K2's Z-clip system is simple, secure, and it attaches in a flash. You'll be hard-pressed to find a pair of 150mm wide skins elsewhere, much less skins designed specifically for the Petitor. An Offset Skin Cutter is included, which makes it easy to match these skins to the shape and width of your skis on the first try.
