Assos Racing NS Skin Layer P1 2026 Sleeveless Base Layer

The Racing NS Skin Layer P1 is the lightest and most cooling base layer ever developed by ASSOS, designed for the hottest racing conditions and high-intensity efforts.

Its ultra-open mesh construction promotes maximum airflow directly against the skin, accelerating the wicking away of heat and internal moisture. The low-water-absorption fabric prevents any feeling of saturation, even during prolonged efforts or repeated sprints.

The sleeveless design and flat-lock seams drastically reduce bulk and chafing, allowing the Skin Layer to disappear completely under a racing jersey. Its racingFit cut hugs the body like a second skin, ensuring optimal contact for effective thermal management without compromising freedom of movement.

The result: an almost imperceptible base layer, designed to maintain a dry, cool and stable microclimate when temperatures exceed 21°C and intensity is at its peak.
