Vapor Barrier X
100% Waterproof Cold-Weather Boots
About The Technology
Vapor Barrier X functions as a waterproof layer that fully encloses the insulation on all sides, blocking moisture penetration from both the exterior and interior of the boot. This barrier prevents wetness and condensation from compromising performance. As a result, the insulation stays dry, protected, and able to deliver consistent warmth in demanding conditions.
Waterproof
Windproof
Coldproof
Cold-weather boots use insulation to create a thermal barrier to keep your body heat in and the cold out. Wet insulation kills heat retention which is why many winter boots have waterproof features.
But exterior waterproofing alone isn't enough.
When cold-weather boots work well, your feet sweat, that interior moisture penetrates the insulation and over time leads to heat loss.
Vapor Barrier X™ technology solves this problem.
By sealing the insulation between two waterproof layers, it keeps insulation completely dry—preserving the thermal barrier, keeping your feet warm for countless hours no matter the conditions.
