Light insulation, seamless comfort, and full-arm coverage in a long-sleeve base layer for colder conditions encountered in late fall and early spring. It's crucial that our upper body gets an added boost against the elements during those cold fall and early spring conditions. As a solution, we developed the Spring/Fall LS Skin Layer, which has taken the torch from our iconic Skinfoil base layers with a completely revamped design and all-new blend of fibers. To start, we've lowered the weight by about 8% and used a tubular knit technology that's free of irritating side seams. A cool-weather-tuned blend of carbon and polypropylene yarns are employed to pull moisture away from your skin and insulate your core, keeping you dry, insulated, and comfortable from the outset. The thicker Circular Seamless construction introduces a tubular knit that's free of side seams, creating an ultrasoft, comfortable feel against the body. The sleeves are sewn directly into the armhole to promote a full range of motion beneath additional layers.

A medium-weight, short-sleeve base layer tuned to keep your core lightly insulated and dry in cool conditions. This protective layer sets the foundation of our ASSOS Layering System, doing the job of keeping your upper half lightly insulated and dry in the cool, challenging conditions of spring and fall. Having been tested over and over again by our product team until we were finally satisfied, the Spring/Fall SS Skin Layer represents a total first-layer reset. A cool-weather-tuned blend of carbon and polypropylene yarns are employed to pull moisture away from your skin and insulate your core, keeping you dry, insulated, and comfortable from the outset. The thicker Circular Seamless construction introduces a tubular knit that's free of side seams, creating an ultrasoft, comfortable feel against the body. The sleeves are sewn directly into the armhole to promote a full range of motion beneath additional layers.

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. 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. 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.
