Breathable Waterproof

Polartec® NeoShell® is the world's most breathable waterproof fabric technology.

For years the outerwear industry has prioritized excessively high waterproof ratings that sacrifice the breathable performance needed during physical activity. Neoshell® provides the strength and durability of a weather protective fabric, while still allowing dynamic air exchange and comfortable full range of motion.

Stay Dry. Inside And Out.

About NeoShell® Technology

Polartec® NeoShell® allows more breathability through its sub-micron membrane structure at the core of the fabric.

By engineering optimal pore size and placement, NeoShell® releases heat and perspiration without high pressure build up. Continuous air exchange enhances natural thermoregulation, while still providing the needed protection from all outside elements.
