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.

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.
