ASSOS BODY INSULATOR Ultraz Winter Long Sleeve Skin Layer Undershirt - calypsoBlue

The Ultraz Winter LS Skin Layer brings maximum thermal protection and body-mapped comfort to your coldest rides, courtesy of a new wool-blend knit and seamless construction. 

Building on the protective Winter LS Skin Layer, the Ultraz edition turns up the warmth and windblocking capabilities even further with its wool-blended knit. Assos 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, Skin Layer is a total reset on the base layers of yore, wearing a completely revamped, lighter makeup and using a new blend of fibers. This 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.
