Description
The P1 X‑Flow Slim Fit Top in Black is uncompromising high‑performance racing underwear for drivers who need maximum control over their body climate under extreme conditions. Developed for professional motorsport as well as ambitious club racers, this top fully meets the FIA 8856‑2018 homologation and is therefore approved for all competitions where FIA‑certified underwear is required.
The X‑Flow series is based on P1 Racing’s most advanced underwear technology to date. A specially engineered open fabric structure ensures exceptionally high airflow and rapid moisture transport. Heat is efficiently dissipated from the body, significantly reducing heat build‑up under the race suit – a clear advantage during long stints, endurance races, or rally stages.
With an extremely low material weight, the X‑Flow Slim Fit Top is one of the lightest FIA‑approved underwear garments worldwide and up to 60% lighter than conventional FIA underwear. At the same time, it achieves 2 to 10 times higher breathability compared to many competing products. The result: less fatigue, more stable concentration, and consistent performance throughout the entire race distance.
The fabric is exceptionally soft, elastic, and ergonomically designed. The slim‑fit cut sits close to the body without restricting movement and ensures an optimal fit under the race suit. Functional stretch zones adapt to the seated driving position and allow full freedom of movement – both inside the car and when getting out or moving around the paddock. The black version offers a professional, understated look and is especially popular with teams due to its reduced susceptibility to discoloration.
Available in a very wide range of sizes, including junior, women’s, and large sizes. All P1 FIA tops are suitable for professional logo printing and sponsor branding. Information on printing options, lead times, and pricing is available upon request.
