The Air Tech Crampon by Grivel is part of a new generation of crampons. Ten points in contact with ice while you're walking, 12 that bite into the slope during traverses. This has been made possible because the third pair of points are shorter and wider apart. On top of this the last two front points have a double angulation to maintain bite when descending or traversing sideways. The crampons points are short and designed for the new requirements of "mixed modern's" alternating ice and rock. Sharp points are ideal for anchoring on ice "cauliflowers" and when in traction or adherence. Even the soles of the most modern boots are perfectly covered. Semi-rigid model in one adjustable size. The bar can be regulated by hand, in two different lengths. These New versions have a new binding made in "bi-components" giving greater efficiency and lightness. It is really an "all seasons" crampon, very light and takes up a minimum of space as it folds up completely on itself.
