Here's what other sites are saying:
Toss that skin-trimming tool in your junk drawer because the K2 DarkSide Climbing Skins are pre-cut to match your K2 DarkSide skis, and that's going to save you some serious hassle. Your DarkSide skis already have holes in the tips (behind that rivet hardware) that are designed specifically to accommodate compatible K2 Z-Clip attachments. All you have to do is clip the tip, adjust the tail to length, and get sliding up the hill. See, climbing skins are nothing to be afraid of (unlike yetis).
Skin up the sidecountry on your K2 DarkSide skis when you use the pre-cut DarkSide Skins. Don't worry about trimming to fit because that's already been done for you. Pull them out of the box, slap them on your skis using the tip and tail holes, and skin up some fresh tracks.

Designed exclusively for the K2 DarkSide skis (sold separately), these K2 climbing skins feature an innovative attachment system to reduce weight and friction. Z Clip tip attachment hooks onto the hole at the tip of K2 DarkSide skis; sleek design keeps weight low and helps prevent snow from building up where the skin meets the ski. Adjustable tail strap interfaces with the tail hole on DarkSide skis to secure the skin; clip sits on top of the ski rather than at the back, thereby reducing drag. Choose the length that matches your ski length; width of the skin is pretrimmed to match the sidecut of the K2 DarkSide skis. Include Glue Saver mesh storage sheets, detailed instructions and a nylon storage bag.
