Polartec, LLC introduced Polartec NeoShell, its first waterproof/breathable fabric. NeoShell will appear in Fall 2011 collections from some of the leading outdoor apparel brands, including 66 North, Eider, Mammut, Marmot, Montura, Rab, The North Face, Vaude and Westcomb.
Polartec NeoShell is completely waterproof (10,000mm) but unlike most hardshells on the market today with zero airflow, NeoShell allows actual air permeability (0.5 CFM or 2 l/m2/sec), Polartec said. While traditional shell fabrics require heat and pressure to build inside the garment before the membrane begins to work, Polartec NeoShell breathes actively thanks to an exclusive sub-micron fiber membrane with unprecedented air permeability.
That is a small thread from SportsOneSource on the new fabric. Marmot is coming out with a shell next fall called the Zion for both Men and Women. It looks good and I can wait to actually use it on a wet Ice climb!
