Modular ice axe for technical mountaineering The SUM'TEC ice axe represents versatility: it adapts easily to any mountaineering activity, from classic to technical. It is completely modular, allowing it to be optimized for the objective. The TRIGREST handrest, adjustable without tools, and the compatibility of the ice axe with most Petzl accessories (PUR'ICE and DRY picks, MASSELOTTES...) ensure the efficiency required for difficult sections.
