The Summer NS Skin Layer serves as your first line of defense during the hottest days of the year, managing moisture, regulating temperature, and keeping your body cool with its ultralight yarns and seamless design. Unassuming, hidden from view, and working overtime to keep your core temperature regulated at all times. The humble summer first layer is often an afterthought, but we take it seriously, constantly refining its composition and silhouette to ensure it keeps you comfortable during the balmiest days of the year. A new blend of carbon and polypropylene yarns have been strategically arranged to manage moisture much better than previous iterations, resulting in a breathable, antibacterial short-sleeved first layer that keeps you cool and dry from the base up. The Circular Seamless construction introduces a tubular knit that's free of side seams, creating an ultrasoft, comfortable feel against the body.
