Capilene® 4 Expedition Weight products will now utilize Polartec® Power Dry® High Efficiency™ fabrics starting with the Autumn/Winter 2012 season. By exaggerating the gaps between pillars on the back of the fabric, the breathability of the fabric is enhanced, as is the compressibility and warmth-to-weight ratio. The new Capilene 4 Expedition Weight is light enough to wear very comfortably next to skin, warmer than expected based on weight, and like all Polartec Power Dry fabrics, it utilizes a bi-component construction designed to pull moisture in one direction – away from the body – and then disperse it to the surface for quick drying performance. The new fabric is 91% polyester/9% spandex, with great stretch and recovery.
