OutDry uses a one-piece patented construction process that creates a waterproof, breathable barrier in footwear and gloves. This impenetrable layer is heat bonded directly to the outer fabric, leaving no seams, no gaps, and no way for water to get in. Compare that to traditional water proof technology; water gets in and stays in, collecting in the space between the inner and outer layers, making them heavy and wet. OutDry improves fit and dexterity, keeping you drier, lighter, and more comfortable. OutDry, the one that keeps you dry.
