Undergarments

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.
