The new benchmark for high altitude technical mountaineering. Ideal for ice climbing and climbing big walls, technical treks in winter conditions and staying in extreme places at low temperatures. G-Summit was developed with the aim of satisfying a double need: an extremely thermal product for high altitude mountaineering and a surprisingly light and precise double boot for expeditions in highly challenging climates. In fact, thanks to the special removable liner, G-Summit turns is a customisable product based on the thermal requirements of the terrain and environment of use.
