Tuned for the cold, demanding conditions of winter riding, the Winter LS Skin Layer's insulating knit structure and seamless construction join forces to keep you dry and insulated from the base up.

Temperature regulation is the key performance indicator of any base layer, and this is especially true for a winter version. But winter poses a specific host of challenges not found in other climaCodes, namely in the form of added cold air and your additional layers. This is where Assos' new Winter LS Skin Layer fills the gap, tuned with a thicker knit weight, taller collar, and more stretch than the Spring/Fall version for boosted insulation and flexibility under your outer apparel.

It's worth noting the Skin Layer is a total reset on Assos' base layers of the past, wearing a completely revamped design and using a new blend of fibers. The Winter LS is roughly 13% lighter than the previous Winter Skinfoil, relying on a Circular Seamless construction that's free of irritating side seams. A winter-tuned blend of carbon and polypropylene yarns‚ plus elastane‚ are employed, which draws moisture away from your skin and insulates your core, keeping you dry, insulated, and comfortable from the outset.

Circular Seamless: A tubular knit technology that's free of side seams, creating an ultrasoft, comfortable feel against the body.

Set-In Sleeves: Sleeves are sewn directly into the armhole, promoting a full range of motion beneath additional layers.

Composition: 91% polypropylene, 6% elastane, 3% carbon fiber
