Boreal G1 Expe

Size (UK)
1 item left

The G1 Expe is the result of an ongoing dedication to make the finest high altitude boots in the world. Boreal understands that at the rarefied extremes of high altitude mountaineering the right equipment can make all the difference and this is why G1 Expe has been carefully designed, field tested and refined to guarantee exceptional levels of performance and reliability, without compromise.

Description

G1 Expe is a triple layer boot consisting of an integrated outer gaiter, mid layer ‘shell’ and a removable inner bootie. The outer gaiter has a soft and comfortable elasticated cuff with both zip and strap closures for failsafe reliability. The lower portion of the gaiter is insulated with encapsulated layers of triple Thinsulate™ and polyethylene and is reinforced with an extremely rip resistant material in the high wear zones.  A new synthetic rand material has been used which is lighter and warmer than rubber and won’t perish in the high U.V light conditions found at high altitude.  The outer surface of the mid-layer boot in constructed from entirely from lightweight synthetic textile and lined with a tough and waterproof/breathable Cordura reinforced laminate. Sandwiched between is a 6mm layer of EVA foam for excellent thermal insulation.

A new much lighter sole unit module has been developed with dual density crampon attachment lugs, hard at the back for a positive crampon fit and soft at the front which provides welcome vibration absorption when front pointing on hard ice. Our ultra lightweight yet rigid carbon fiber composite midsole provides a considerable weight saving and an incredibly lightweight low density Vibram Betulla outsole with is designed for optimum performance above the snow line completes the package.
