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.
