The Masselottes by PETZL are weights for ice tools and ice axes for technical mountaineering, ice climbing and drytooling.

The weights are positioned on each side of the pick. The balance of the ice axe during the strike is improved for precise placements in hard ice. The shape of the weights optimizes slotting the pick into cracks. The Masselottes by PETZL are removable, to adjust the technical aspects and weight of the ice axe for the route.

The Masselottes by PETZL are compatible with the ice tools Sum'Tec, Gully, Quark, Nomic and Ergonimic.
