Details
Maximum thermal protection and body-mapped comfort in a long-sleeved base layer, tuned for the coldest, most demanding winter riding conditions.
Building on our protective Winter LS Skin Layer, the Ultraz edition turns up the warmth and windblocking capabilities even further with its wool-blended knit. 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.
Technology
Featured Fabrics
A robust arctic-tuned blend of polypropylene and wool are employed, serving as the ultimate next-to-skin foundation when maximum thermal- and windblocking-protection are most critical.
Construction / Fit
The Ultraz relies on a Circular Seamless construction that’s both ultrasoft and free of irritating side seams. The sleeves are sewn directly into the armholes to promote a full range of motion beneath additional layers.
