The Air Tech NM crampon is such a good all round crampon. It is lightweight & can pack down by folding up on itself to take up minimum space. The 12 points give great traction on snow & ice & the last two side front points have a nice purpose; the double angulation of these points maintain biting capabilities when descending or traversing sideways giving you more stability. The crampons points are short & designed for the new requirements of “mixed modern’s” alternating between ice & rock. Even the soles of the most modern boots are perfectly covered. The Air Tech is a semi-rigid model & is fully adjustable, the bar can be regulated by hand so there is no need for tools. Grivel recommend that these crampons are perfect for Classic & Technical Alpinism as well as Scottish Winter Mountaineering Light weight Adjustable No tools needed, Strong & durable New-Matic binding style Anti-balling plate
