## Assos WOM 3/3 LS Skin Layer (Winter, Women's)

The Assos WOM 3/3 LS Skin Layer is a long-sleeved **base layer** for cold, demanding winter rides and forms the foundation of a functional layering system. Its insulating knit structure and **seamless** design keep you warm and dry from the first layer without adding bulk. Compared to the spring/autumn counterpart, the fabric is deliberately **thicker**, the **collar higher**, and the stretch greater, so insulation works even better under additional layers. The material blend of **polypropylene**, **elastane**, and **carbon fiber** rapidly transports moisture away from the skin and stabilizes the microclimate even during intense intervals. This model is designed for female riders who train in Switzerland even in biting winds or on snow-covered Alpine passes, relying on a precise **Second-Skin Fit**. Two variants are available, with the updated P1 version bringing additional fine-tuning details for protection and breathability.

- **climaCode 3/3 Winter**: women's base layer specifically tuned for winter conditions  
- **Circular Seamless**: circular-knit, virtually **seamless** construction for high wearing comfort  
- **Raglan sleeves**: unrestricted freedom of movement in the drops and when shoulder-checking  
- **Material**: 91% polypropylene / 6% elastane / 3% carbon fiber for **moisture management** and insulation  
- **Higher collar** and **thicker knit structure** than the Spring/Fall model  
- **Second-Skin Fit**: close-fitting cut for efficient thermoregulation under winter jackets  
- **P1** variant: refined protection zones and increased **breathability** plus permanent **odorControl** properties  
- Color: **blackSeries**; sizes 0–III (Assos sizing system) 

## Technical Details and Functions

The **Circular Seamless** construction eliminates disruptive side seams and lays the foundation for a smooth, friction-free fit under jerseys, gilets, and winter jackets. Front and back panels are connected with **raglan sleeves**, allowing the seam line to extend up to the collar and maximizing freedom of movement in the saddle. The synthetic blend with **carbon fibers** promotes quick drying, actively wicks moisture, and helps maintain stable body climate. In the updated **P1 variant**, the insulation structure is knitted denser at the front against windchill and more open at the back, creating a better balance between warmth and **breathability**. Additionally, the P1 version offers permanent **odorControl** that reduces odor formation long-term. The result is a base layer that fits like a second skin and optimally utilizes the textile's **push-pull** properties.

## Applications and Benefits

As the first layer under **winter jackets**, **thermal bibtights**, and windproof gear, the WOM 3/3 LS Skin Layer is ideal for road cycling, gravel, and daily commuting in Swiss winters. The combination of **insulation** and **moisture management** prevents cooling on descents and minimizes overheating on climbs. The **high collar** reduces drafts in the neck area without restricting mobility. Thanks to the low-seam construction, this layer doesn't add bulk even under close-fitting jackets and feels comfortable even on long base training rides. Independent tests highlight the strong **thermal performance** and high **comfort** of the Assos Winter LS Skin Layer, making it a popular choice for consistent winter training. This way you benefit from a dry, stable microclimate – whether riding along the Limmat or on wintry Jura mountain passes.

Sizes 0 to III follow Assos's proprietary fit system; thanks to the **Second-Skin** cut, the base layer sits close to the body and works best directly on the skin. The **blackSeries** color blends discreetly with existing winter gear, from subtle all-black setups to colorful jackets. The manufacturer provides a **2-year warranty** and recommends this piece as the first layer for cold conditions; depending on your personal cold sensitivity, you can further modulate with neck warmers, vests, or midlayers. Note that the **P1 variant** with zoned knit structure and **odorControl** focuses on maximum precision in protection and breathability, while the standard version already offers a very balanced warmth-moisture ratio. Both variants share the robust, quick-drying yarn blend specifically designed for winter rides.
