Alpine crampons Petzl VASAK FLEXLOCK

Vasak Flexlock are one of the most popular crampons from Petzl for classic mountaineering. If you are planning to hike on technical terrains durring the winter or you go for a classic alpinism these crampons are great option for you. With the system of 12 sharp points they will provide you with the needed stability and secure bite when you go through glaciers or snow couloirs. 

The platform of the crampons is produced from stainless steel for maximum durability. The 12-ve point system is designed to offer great bite and comfort during walking. The front long teeth provide effective traction and solid purchase on hard snow. ANTISNOW system helps limit snow buildup in a variety of snow conditions.

VASAK FLEXLOCK are one of the most versatile crampons from Petzl range. They are compatible with each boot supported for winter hiking, withouth need for special board welts for semi or full automatic crampons. You just need to pick a boot with stiff outsole and grip reccomened for snowly conditions and you are ready to go. 

IRVIS FLEXLOCK and VASAK FLEXLOCK models 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.

All Petzl crampons have Anti-Snow, 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.

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. 


VASAK FLEXLOCK biposition linking bars make the crampons compatible with large range of boots (size 36 to 50).
