With its wool-blended knit, the Women’s Ultraz Winter LS Skin Layer turns up the warmth and windblocking capabilities to the max. We see this as the ultimate defensive first layer in the most challenging winter conditions, as it goes into overdrive at the core level to keep you dry and your temperature stable.

Setting a new foundation, this Skin Layer is a total reset on our base layers of yore, wearing a completely revamped, female-specific makeup and using a new blend of fibers. The Ultraz model is about 10% lighter than the previous Winter LS Skinfoil, relying on a Circular Seamless construction that’s both ultrasoft and free of irritating side seams. A robust arctic-tuned blend of polypropylene and wool are also employed, serving as the ultimate next-to-skin foundation when maximum thermal- and windblocking- protection are most critical.
Circular Seamless: A tubular knit technology that’s free of side seams, creating an ultrasoft, comfortable feel against the body.

Raglan Cut: Sleeve design free of a traditional shoulder seam, continuing up to the neck for greater range of motion.

Composition: 50% polypropylene, 31% wool, 10% polyamide, 6% elastane, 3% carbon fiber
