Endurance Cap P1

Assos Endurance Cap P1

The Assos Endurance Cap P1 is the classic cycling cap, reimagined with modern materials for active moisture management and quick-drying comfort. Instead of cotton, Assos uses 100% polyester here, keeping your head pleasantly cool in warm conditions. The design remains deliberately timeless with a distinctive contrast stripe down the middle. Thanks to One Size (OS), the cap fits easily under standard road bike helmets and provides shade plus light protection from drizzle.

Technical Details and Features

The cap is based on a lightweight, robust polyester construction that quickly wicks moisture away from your head and promotes evaporation. Its flat peak fits well under modern road helmets and can be easily angled when needed. Assos offers the Endurance Cap P1 as a One Size (OS) model, which simplifies size selection and ensures a comfortable fit for most head sizes. The colour palette includes Black Series, White Series, Edge Green and Golden Yellow; internal model designation: P13.70.771.

Applications and Benefits

Whether commuting in Zurich, tackling long passes in Valais or a quick after-work loop around Lake Zurich – this cap delivers reliable performance on your road bike and when gravel riding. Worn under your helmet, it helps keep sweat away from your forehead and eyes, while the peak improves visibility in sun and light rain. It's precisely this combination of weather protection and wearing comfort that's made cycling caps popular for decades. The Endurance Cap P1 combines this tradition with contemporary function for everyday use as well as long tours.

Variants and Style

For the Swiss cycling scene, looks matter too: the cap is available in Black Series, White Series, Edge Green and Golden Yellow, making it easy to coordinate with jerseys and socks from the current Assos range. The central contrast stripe creates a clean, classic statement – on and off the bike. If you value easy care and quick drying, you'll particularly appreciate the technical polyester fabric on warm days or during indoor training. This way, the cap stays pleasantly fresh and ready to go even after intense intervals or long Alpine stages.
