what a brilliant idea in the first moment, unfortunately turns out to be risk. Clamped it runs well, to fold down brauchts some practice. Unfortunately, the second clip has been broken without any external assistance, and the crampon drops like a loose tooth. If that happens to you on a slope, stehste there and not come back or forward, I prefer the old version, which has to be transported up the backpack. The extremely thin-held clamp is made of plastic, which is a stable solution is not really related to the cold. The should also be made of metal. , , ,
