The Straps on a Ski-Lash Jr. are 12 1/2 inches long and are designed for carrying skis of 120 cm in length or less. Ski-Lash Jr. will also work on skis up to 140 cm if you are not carrying poles.
If, however, the skis have a raised binding, a standard size Ski-Lash may be appropriate. To make certain, wrap a tape measure around the skis (and poles, if carrying them) inside of the bindings as close to the toe binding as possible. If that measurement is greater than 11.5 inches, use a standard size Ski-Lash.
