The Vasak is a 12-point general mountaineering crampon designed for introductory and classic alpine mountaineering terrain when most travel is on glaciers, classic snow and ice faces and mixed rocky ridges.
Petzl have designed two ways of fixing the crampons onto the heel of your boots.
The first is the Flexlock heel fixing system, which fixes onto all types of mountain boots from flexible B1 to more rigid B3 boots.
The second is the Leverlock system, which requires a heel welt moulded onto the sole unit of your boot, allowing the locking system to lever onto it and fix securely. These boots are typically the stiffer B2 and B3 boots.
At the front point end of the crampon, Petzl have also designed two ways of securely fixing the crampon to the toe of your boots.
The first is a rubber moulded flexible bail that fits over the toe of your boot. This is designed for B1 and B2 boots that don’t have a toe welt moulded onto the sole of the boot. It also works well on boots that have a moulded toe welt, but which, over the years, has worn down through walking and isn’t now big enough to secure the second system!
The second system is a metal toe bail that fixes onto the moulded welt that you’ll find on some B2 and all B3 boots.
General alpine mountaineering crampons seem to last much longer than boots these days and with this in mind many people favour the rubber moulded flexible bail fixing for the toe of their boot and for speed and efficiency they use the Leverlock system to secure the heel of the boot as many people will use B2 boots in the summer.
These days, all crampons come with integrated anti-ball plates and Petzl have designed the ANTISNOW system to stop any wet snow from balling up underneath the crampon.
On the Vasak there are two FLAT front points designed for snow, ice and rock climbing on more classic and glacial terrain, perfect for our introductory and classic alpine mountaineering courses.
