SURFACE HARDENED™ THERMAL WOOL

SURFACE HARDENED™ Thermal Wool is our answer to the demand for a tougher breed of mid-layer wool. Soft, comfortable, and warm enough to live in, this unique construction features a durable 21.5-micron wool reinforced by an array of outer-facing nylon fibers. Finished off with a durable water repellent (DWR) coating, this backcountry fabric is built to work equally well under a shell or alone.
