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.

Pas Normal Studios
This undershirt is not just a baselayer. The materials that Pas Normal Studios has used are effective because it perfectly keeps your body cool due to the moisture-wicking qualities of the polyester. The undershirt feels very soft against the skin and on the back is written in large letters 'ROAD TO NOWHERE' and on the front of course the Pas Normal Studios logo. Very cool as far as we're concerned!

Canvas
Comfort starts at the base. This merino midweight baselayer from Amsterdam-based brand Canvas combines qualities of natural and sustainable (RSPCA approved) wool with recycled (GRC certified) polyester fibres. Creating a soft-to-the-touch baselayer that keeps you warm and dry in colder weather. Made from sustainable materials in Europe, this layer is one you will reach for when you go for longer rides in autumn, winter or spring. Canvas designed the fit to be not too constricting, with a slightly longer body so you can also use it while hiking, skiing or for other 'winter' activities. The neck is cut lower so it won't interfere with other layers and you can add the merino neck warmer for extra warmth and comfort.
The fit is snug but relaxed and runs true. Our Model Ewout is 1.85 and wears a size Medium.
