An extremely comfortable and warm BC-boot with an integrated gaiter that is reinforced with Kevlar on exposed areas. The boot has been developed specifically for expeditions and long journeys on skis in extremely cold conditions. Polar A/P/S also has a specially developed last that ensures you have room for liner or wool inner boots and if necessary vapour barrier socks. It also has extra insulation within the sole and liner. The boot has been used on a wide range of expeditions, both to the North and South Poles, however, it is also suitable for simpler expeditions in cold conditions. Liners or wool inner boots and vapour barrier socks are purchased separately. We recommend buying the boot 2 sizes larger than normal for use during extreme conditions.
