An exceptional boot for mountaineering at altitude, the G5 gives performance you can rely on. Combining the thermal insulating characteristics of a double boot with the lightness and low volume of a single boot, it's well suited to winter alpinism.

A water-repellent, abrasion resistant Cordura gaiter protects the insulated inner boot, which is adjustable via the Boa Lacing System. Together they provide warmth, security and weather protection in a design that is quick and easy to fit. Superlight PU TechLite on the rand and carbon fibre in the midsole help shave weight and bulk, while still providing the durability and performance needed to succeed in harsh mountain environments.
