The best summer base layers are unassuming, hidden from view, and working overtime to keep your core temperature regulated at all times. The Assos NS Skin Layer is nearly 30% lighter than its incredibly effective and popular sleeveless skinFoil predecessor. It has a thin dual surface design, thanks to the new fabric blend and construction. The feel of the skin layer is ultrasoft, less of a true mesh than the skinFoil.

The humble summer first layer is often an afterthought, but Assos takes it seriously, constantly refining its composition and silhouette to ensure it keeps you comfortable during the balmiest days of the year. The Circular Seamless construction process leaves the resulting garment free of any irritating side seams, creating a uniform tubular knit that feel light and impressively comfortable against the skin. A new blend of carbon and polypropylene yarns are now used, managing moisture much better than previous iterations. The result is an ultralight, breathable, antibacterial first layer that keeps your core as cool and dry as possible.
