LAYER NUMBER ONE

The first layer that touches your skin. The last one you remove. The foundation of the ASSOS Layering System, managing the moisture and heat your body generates, delivering seamless compressive comfort, and ensuring you remain dry and protected in every condition imaginable.

START WITH SEAMLESS

While traditional base layers rely on a series of seams to join fabric panels, each Skin Layer is knit with a circular seamless construction for the smoothest, frictionless feel next to your skin.

CLIMATE CONTROL

Carbon fibers are blended into our yarns to more efficiently draw moisture off your skin, while wool is added to our deep-winter layers for natural, heat-trapping warmth. The result? Unmatched temperature regulation, 365 days a year.

CONQUER THE CONDITIONS

Building on our legendary Skinfoil line, the Skin Layer system comprises six male- and female-specific base layers, each constructed with fits, sleeve lengths, and knit structures that match your body and the conditions of your ride.

WINTER SKIN LAYER

Constructed with a thicker knit, taller collar, and more stretch than our Spring/Fall options for boosted insulation and flexibility under multiple outer layers.

ULTRAZ WINTER SKIN LAYER

Maximum thermal protection and body-mapped comfort for your coldest winter rides, courtesy of our new wool-blend knit and seamless construction.
