Using a classic tip loop and tail clip, this skin can be attached easily to almost any ski on the market, and with minimal work.

Straight: There are two schools of thought on the selection and fit of g3 climbing skins, shaped or straight. Shaped: You can get maximum skin coverage by choosing a skin that is slightly narrower than the widest par of your ski, and trimming the skin to the sidecutshape of your ski, as described int the skin instructionsin the box when you buy a pair. The extra work required to trim will more than make up for itself with the superior grip of a skin with wall to wall coverage, especially important for icy sidehilling. Choose the skin that covers your ski base 'Wall to Wall edge to edge about 25cm 10in back from the ski tip. E.g. If the dimensions of your skis are 115 77 105, a pair of 110 skins will do nicely. Straight: To avoid trimming, choose a skin to fit the narrowest part of your ski. This set up is lighter, glides better and eliminates the possibility of contaminating exposed glue when storing skins. Straight skins are also easier to fold for packing and storage. E.g. If the dimensions of your skis are 115 77 105, a pair of 70mm skins will do the trick. Every pair of G3 High Performance Climbing Skins is equipped with a Cool G3 trim tool and specific instructions for fitting your skis.
