Headband P1

ASSOS Headband P1

The ASSOS Headband P1 is an ultralight headband for hot conditions and long climbs in the Swiss summer season. It actively regulates sweat management, so that during intense intervals, Alpine passes or commuting in Zurich sweat doesn't run into your eyes. The flat fit practically disappears friction-free under the helmet and stays stable even on fast descents. Available in the color Grey Series and in size III, it is designed for minimal weight and maximum breathability.

• Ultraleichtes, schnell trocknendes Stirnband für heisse Sommertage im Radsport.

• Circular Seamless construction without seams – no pressure points, no chafing.
• Low-Profile-Fit that practically doesn't add bulk under the helmet.

• Size: III (as specified by the manufacturer) for a contoured fit.
• Designed to ensure clear vision on long climbs and fast descents.

Technical details and features

The P1 relies on an especially ultra-breathable textile made from fast-drying polypropylene yarns that wicks moisture away from the skin quickly and thus supports a stable microclimate. The Circular Seamless circular-knit construction is seamless, lies flat and minimizes friction when layering under the helmet. According to the manufacturer, breathability has been increased compared to the previous version, which keeps the headband noticeably drier during heat periods. Material composition is 84% polypropylene, 13% polyamide and 3% elastane, which explains the mix of moisture management, elasticity and dimensional stability. Taken together, this results in a lightweight, unobtrusive companion that keeps vision clear while increasing wearing comfort on long rides.

Use cases and benefits

Whether race bike laps on the Uetliberg, marathon gravel in the Mittelland or indoor training on the trainer: the Headband P1 prevents annoying sweat drops and keeps the forehead pleasantly dry. In hot conditions, glasses stay clearer for longer, which increases safety especially on technical descents and in urban traffic. It barely adds bulk under the helmet, making it suitable for long days in the saddle or fast commutes. Thanks to the seamless, close-fitting construction it sits reliably without creating pressure points, helping you concentrate on cadence, line and rhythm.
