Description
The P1 X-Flow Top is a next-generation racing base layer engineered for drivers who compete under demanding conditions and require maximum performance from their FIA underwear. Designed for professional motorsport and advanced club-level racing, it fully complies with FIA 8856-2018 while delivering class-leading breathability and ultra-low weight.
X-Flow represents the most advanced FIA-approved underwear technology developed by P1 Racing. Its innovative fabric construction actively disperses heat and moisture away from the body, significantly improving airflow inside the race suit. This results in a noticeably cooler and more stable body temperature, even during long stints, endurance races or high-temperature rally stages.
With a construction that is up to 60 % lighter than conventional FIA underwear, the X-Flow Top is widely regarded as the lightest FIA-approved racing underwear available worldwide. Independent testing shows between two and ten times higher breathability compared to competing brands, making it a decisive advantage in terms of comfort and driver focus.
The fabric is exceptionally soft and elastic, with strategically placed stretch zones that adapt to the driver’s posture. The fit is precise without being restrictive, allowing unrestricted movement both inside the cockpit and when moving around the paddock.
Available in black or white, with additional colours planned. A comprehensive size range includes junior, ladies and larger-fit options.
All P1 FIA tops can be custom printed with team or sponsor logos. Please contact us for branding options, lead times and pricing.
