## Assos Summer SS Skin Layer P1

The Assos Summer SS Skin Layer P1 is the advanced summer base layer generation for hot rides in Switzerland. The new textile blend is **15% lighter**, more elastic and even more breathable – ideal as a first layer under road, gravel or MTB jerseys. The short-sleeve design has been tuned so that **collar shape and sleeve length** harmonise with regularFit and racingFit jerseys and add minimal bulk when layering. The material uses an **open-structured Circular Seamless Mesh** with permanent odour-inhibiting, carbon-based properties that remain effective even after washing.

- **68% polypropylene / 29% polyamide / 3% carbon fibre** for efficient moisture management and long durability.
- **Circular Seamless** knit construction for seamless feel and low volume under the jersey.
- **Second-skin fit** for body-hugging fit and rapid sweat wicking directly on the skin.
- **Permanent odour control** through carbon-infused yarns.
- **Summer 1/3 Layering System**: blends discreetly under RS, GT or TRAIL jerseys.
- **Two variants** available: short sleeve (SS) for slightly more coverage and sleeveless (NS) for maximum ventilation.
- **Grey Series** colouring and sizes depending on availability from 0 to III.

## Technical Details and Functions

The core is an **open, ultra-elastic mesh** in Circular-Seamless construction that allows airflow directly to the skin, creating a noticeable cooling effect. At the same time, the blend of polypropylene and polyamide ensures quick drying, while **carbon fibres** contribute permanent odour inhibition. The **second-skin fit** enables layering with very low volume and prevents bunching under tight-fitting jerseys. Assos has tuned the **low collar shape** and **sleeve lengths** to match the cuts of modern endurance and race-oriented jerseys. The result is a technical base layer that's lighter, more elastic and more breathable than its predecessor.

## Applications and Benefits

The Summer SS Skin Layer P1 shows its strengths on hot Alpine passes, fast after-work rides in the Mittelland and summer gravel adventures. Under high intensities, the material supports **moisture wicking**, keeping jersey and body dry longer and reducing friction. Thanks to the seamless construction, the layer feels unobtrusive even on long distances and minimises potential **chafing points** under jersey sleeves or straps. In practice, the base layer disappears under RS, GT or TRAIL jerseys and fits seamlessly into the **Assos 1/3 Summer** layering concept. Specialist media generally emphasise the combination of synthetic fibres and carbon in Assos base layers for effective moisture management in intensive use.

## Care, Warranty and Fit Advice

As a **dealer tip**, we recommend drying the base layer quickly after rides and washing, and following the care instructions on the label to maintain fibre performance. The body-hugging fit is intentional; if you're between two sizes, choose the tighter option for race-oriented use so the **second-skin fit** works optimally. Assos backs the item with **2 years warranty** plus a **Crash Policy**, which additionally secures the longevity of the piece. Thanks to the lightweight construction, the P1 is also suitable as a travel and training companion, as it dries quickly and takes up hardly any space in luggage.

## Variants and Compatibility

Besides the short-sleeve SS version, there's the **NS variant (sleeveless)** for maximum ventilation on very hot days or under particularly tight jerseys. Both variants belong to the **Grey Series** and are tuned to become practically invisible under RS, GT and TRAIL jerseys. For female riders, there are separately developed **Women's Summer SS Skin Layer P1** models with the same material and functional basis. This way, everyone finds the right balance of coverage, ventilation and layering comfort for the Swiss summer.
