Waterproof technology has remained about the same since the very first
hard shell. Breathability is achieved through diffusion: moisture and
heat create enough pressure that moisture vapor finally passes through
the fabric. Soft shells trade waterproofness for greater breathability
by making use of convection: a constant exchange of air allows more
moisture vapor to escape.
Now, Polartec® NeoShell® delivers the best of both worlds. Its exclusive
membrane allows air to pull moisture vapor out – even at extremely low
levels of pressure. So it helps keep you drier during high-exertion
activities. Polartec NeoShell is the first-ever fabric to enable peak
performance in any condition. It’s time to be liberated.
