## Assos Summer Headband Foil P1 – Grey Series

The Assos Summer Headband Foil P1 is an ultralight **summer headband** for ambitious cyclists in Switzerland. The low-seam, reduced-volume construction ensures it's practically imperceptible **under your helmet** while reliably keeping **sweat** away from your forehead. The breathable, **quick-drying** fabric consists of 84% **polypropylene**, 13% polyamide and 3% elastane, and is designed for hot days and intense sessions. Available in the **Grey Series** and as **One Size (OS)**, it fits comfortably on various head shapes thanks to the stretchy material blend. The seamless construction reduces potential friction points and supports a pleasantly cool wearing experience on long summer climbs. It was developed as a functional intermediate layer that supports evaporation and keeps your vision clear.

## Technical Details and Features

Polypropylene fibres are hydrophobic and transport moisture rapidly away from the head, which promotes **evaporative cooling** and creates a dry feeling. Combined with polyamide for durability and elastane for stretch, this creates a thin, form-fitting knit that encourages air circulation and dries quickly. The **seamless** design minimises friction points and ensures a soft wearing experience even during long training sessions or high-intensity intervals. Thanks to its low volume, the headband virtually disappears under your helmet and supports a seamless **layering** strategy on hot days. The construction is specifically designed to catch and distribute **sweat** rather than letting it run into your eyes. This keeps your focus on the road – not on burning eyes.

## Applications and Benefits

Whether tackling long Alpine passes in Ticino, quick after-work loops around Lake Zurich or dusty **gravel** circuits in the Mittelland – the Foil P1 keeps your forehead and temples dry and improves **vision** in the heat. It also excels during **indoor training** under the fan or commuting in changing conditions with rapid moisture wicking. Technical articles show that a light, technical layer in warm conditions can support evaporation – particularly when your jersey doesn't fully handle this task; this is precisely where the Foil P1 comes in as a targeted **sweat management** layer. Thanks to **One Size (OS)** and stretchy material, it sits securely without creating pressure points, and can be quickly rinsed and dried after your ride. If you're looking for clear vision and consistent comfort on hot stages, you'll find a simple, functional solution here for summer conditions in Switzerland.
