Boreal G1 Lite



Careful selection of the best modern materials has enabled us to reduce weight without compromising warmth. G1 Lite is truly a modern classic for winter alpine ascents and 6000m peaks.


    • Crampon: Toe + heel bail - all crampons styles will work (universal, semi-auto, and auto)
    • Bi-Flex: a system developed by Boreal to improve the forward and lateral flexibility of mountain boots around the ankle area. Bi-Flex greatly enhances both the walking comfort and freedom of movement when climbing.
    • A thermal insulation system using Thinsulate® to completely surround the foot with no cold spots. The Thinsulate® lining is fixed in place with minimal use of adhesives to maximize loft. The base of the boot is uniquely insulated with triple Thinsulate® to minimize heat loss through the sole unit.
