Semi-automatic crampons Petzl IRVIS LL UNIVERSEL

Lightweight, compact, and durable, IRVIS crampons are designed for glacier travel, classic mountaineering, and ski touring. The 10-point configuration provides stability for walking on hard snow and digging into ice. THE LEVERLOCK UNIVERSAL system helps them to adapt easyly to boots with heel welts or boots with heel and toe welts. 

IRVIS LEVERLOCK are suitable option for winter trekking, ski touring or hiking through mixed terrains with various snow conditions. The 10-point system is manufactured by steel for maximum durability and provide a secure feeling when walking on ice. 

All Petzl crampons have ANTISNOW system built by anti-balling plates as standard, which stop any wet snow clogging up the underneath of the crampon which would affect your security when walking on such snow.

IRVIS and VASAK models from Petzl are both for snow or glacial walking/general mountaineering, having two flat front points that give good security when kicking into steeper snow and downward pointing walking points, giving good security on flatter snow and ice when ‘flat footing’ (walking).

The key difference in both front sections is that the IRVIS front section is smaller, giving you only four downward pointing walking points and two front points, whilst the Vasak front section has six downward pointing walking points and two front points.

For small feet we would recommend the Irvis front section as there won’t be much gap between the front section and heel plate. Those with larger feet would benefit from the Vasak’s extra two downward pointing walking points giving them that bit extra security when ‘flat footing on snow and ice in both ascent and descent.

The AlPEN ADAPT system used by PETZL is completely modular and allows you to change different moduls from the crampons such as: front section, linking bars, antibott system separately.
