The new reference point for high-altitude technical mountaineering. Ideal for ice and big wall climbing, technical progressions in winter conditions and stays at low temperatures in extreme places. G-Summit was developed with the aim of satisfying a double need: an extremely thermal product for high altitude mountaineering or a surprisingly light and precise double boot for expeditions in very challenging climates. In fact, thanks to the special removable lining, G-Summit turns out to be a customizable product depending on the thermal requirements imposed by the terrain and the environment of use.
