Bon produit


J´ai acheté ces crampons pour mon conjoint, et il en est très satisfait. Ils sont légers et s´adaptent très bien.

Petzl modularity


In recent years Petzl with the modular approach to their design got ahead of the game in every aspect of mountaineering equipment. In this case - I have bought in total 2 pairs of crampons (Leopard FL and Lynx Leverlick Universel) and two front sections (Vasak and Irvis) that allowed me the endless combination of crampons for literally ANY mountain activity from snow approaches in soft B0s to climbing WI6 in fully rigid B3s and anything in between. No need for specialised type of crampon per activity, you take one pair and possibly a front section and some tools and you are sorted for a trip... Magic

Arc black diamond gloves


On the BLACK DIMOND website they are sold as ice climbing gloves. UNUSABLE. A waterfall glove must be perfect on the hand. There is a considerable amount of extra fabric that does not allow you to maneuver anything with ease and simplicity (first of all, the carabiners fit into the excess fabric). Contacted BD not by exhaustive answers. USED ONCE AND PUT IN DRAWER

Crampon tip


Toe bought to transform mountaineering crampons into crampons for easier excursions in a snowy environment, keeping the rear block, gaining lightness.

Petzl crampons


The integration between Petzl crampon components is superior to other brands. A whole crampon already arrives with the interchangeable underwire or cage (for the toe) while buying only a different front block you can have enough combinations for the crampon to be suitable for different types of boots; in short, it is like having multiple crampons and thus being able to cover the various needs in the various activities in an optimized manner; in my case: ski mountaineering, mountaineering, classic, waterfalls with only two front blocks
