The ASSOS Summer NS Skin Layer P1 is a next-generation sleeveless cycling base layer engineered for maximum cooling and moisture management in hot conditions. As part of ASSOS’ refined P1 platform, this summer skin layer is built to function as a true second skin, enhancing thermoregulation and comfort during high-intensity efforts and long rides in elevated temperatures.
Constructed with an ultralight circular knit structure, the Summer NS Skin Layer P1 actively pulls moisture away from the body while promoting continuous airflow. The seamless design eliminates friction points and reduces bulk under a jersey, creating a smooth, low-profile fit. Highly elastic and body-mapped for performance, this sleeveless base layer supports optimal temperature control without restricting movement.

The ASSOS Summer SS Skin Layer P1 is the next evolution of the brand’s hypercooling, ultrabreathable summer base layer, re-engineered to be more elastic, more breathable, and 15% lighter. The new textile blend creates a more body-wrapping shape for an improved second-skin fit, while the more open structure increases cooling airflow and breathability in warm conditions.
Its circular seamless mesh construction is designed for low-volume layering and next-to-skin moisture management, making it a strong choice under both endurance jerseys and more aerodynamic race jerseys. Permanent carbon-infused odour control is built into the fabric and does not diminish after washing, while the deep collar shape and sleeve lengths are designed to align with both regularFit endurance jerseys and second-skin racingFit jerseys.
