The C-Zone membrane helps keep your hands dry and comfortable by providing water resistance while allowing moisture (like sweat) to escape, preventing the build-up of moisture inside the gloves or mittens. Hestra incorporates the C-Zone membrane into a multi-layer system, where it acts as a barrier between the outer fabric and the inner insulation. This helps to prevent snow, rain, and cold air from getting inside, while also allowing moisture from inside the glove to be released. The C-Zone technology is especially helpful in extreme weather conditions, where staying dry is crucial for warmth and comfort.
