Spring Fall LS Skin Layer

Assos Spring Fall LS Skin Layer

When it's cool in the morning and milder in the afternoon, this long-sleeve base layer forms the foundation for smart layering on the bike. It offers light insulation, seamless comfort and full arm coverage – just right for the transitional period from late autumn to early spring days in Switzerland. The current Skin Layer generation builds on the earlier Skinfoil models and features a redesigned construction without disruptive side seams. The material blend with polypropylene, polyamide, elastane and carbon transports moisture quickly and stabilises your core, keeping you dry and focused for longer. This keeps your microclimate balanced, even when the weather suddenly changes between Uetliberg and Lake Zurich.

• Circular Seamless: tubular knit construction without side seams for an exceptionally soft feel
• Second-skin fit: lies close to the body and supports thermoregulation and moisture management
• Material mix: 71% polypropylene, 22% polyamide, 4% elastane, 3% carbon fibre
• Long sleeves with raglan-style cut extending to the neck for freedom of movement
• Lighter than the previous Skinfoil generation, ideal for layering under jersey or jacket
• Developed as the first layer in the ASSOS Layering System for cool conditions
• Sizes according to ASSOS system: 0–III for a precise, close-fitting fit.

Technical Details and Features

The thicker Circular Seamless structure creates an even, low-friction surface – perfect when you're spending many hours in the saddle. The Second-skin fit keeps the fabric close to your body, supporting push-pull moisture wicking and keeping warmth where you need it. The cool-weather blend of polypropylene and carbon fibres quickly draws sweat away from the skin and helps reduce odours. Raglan-style sleeves extending to the neck provide natural freedom of movement when reaching for the drops or looking over your shoulder. The result is a base layer that provides light insulation, dries quickly and is barely noticeable under additional layers.

Applications and Benefits

This long-sleeve base layer is the first choice for cool morning rides in the Zurich lowlands, autumn passes in the Mittelland or wet spring days with Bise winds. As a first layer under a spring/fall jersey or light jacket, it regulates your microclimate and prevents overheating on intervals as well as cooling down on descents. In changeable weather, it can easily be combined with a thin rain shell without adding bulk or restricting mobility. Media generally praise the ASSOS Skin Layer for high comfort and reliable moisture management, which particularly pays off on longer rides. This gives you a versatile foundation for training, commuting, gravel and road bike tours in the Swiss transitional season.

Sizes and Fit

The cut is deliberately close-fitting so that the thermoregulating properties come into full effect and no wrinkles form under jersey or jacket. Thanks to the elastic knit structure, the material adapts to different torso shapes without constricting. With ASSOS sizes 0 to III, you'll find a finely tuned fit that both lies close to the body and offers sufficient freedom of movement for athletic positions. Plan your choice so that the layer can be worn directly on the skin – this is when moisture management works most efficiently. This keeps wearing comfort consistently high even over long distances.
