In 1998 Polartec launched Polartec® Power Shield® and the soft shell revolution. It was developed in recognition of the fact that 90% of the time you are outside, the weather isn't that bad. So there is great benefit in giving up a little weather protection, in order to get a lot more breathability. In 2010, Polartec built on that product history by adding real water resistance to their soft shells with the launch of Polartec® Power Shield® Pro. Polartec® Power Shield® Pro combines never before seen levels of air permeability with durable hydrostatic resistance to keep you dry both from within and from out.
