G-Summit Mountaineering Boot
Winter 2023.24

Published by Mountainblog on .

The new benchmark for high altitude technical mountaineering. Ideal for ice climbing and big walls ascents, technical winter expeditions and prolonged low-temperature exposure. 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.
