The new X-Flow balaclava from P1 has been designed with the professional and advanced clubman competitor in mind, for ultimate breathability while maintaining FIA 8856-2018 standard for eligibility in all events where FIA balaclavas are mandatory. X-Flow balaclavas are available in various colours and sizes, to suit all.

X-Flow is the latest spec of FIA approved underwear from P1 and is highly anticipated to be industry-leading in terms of its breathability and garment weight.

X-Flow is the lightest FIA approved underwear available worldwide, and is 60% lighter than its rivals. The X-Flow range is crucially the most breathable underwear range on the market (between 2 and 10 times better for breathability than competitor brands) and is suitable for all forms of racing and rally competition where an FIA standard is required.

The fit of this range is improved and the fabric is beautifully soft and is able to stretch in the relevant areas to fit your body. This means that with the correct size of garment, you will enjoy improved freedom of movement while seated in the car for long periods of time, or equally whilst walking around the paddock. 

Sizing: P1 X-Flow balaclavas are available in a size structure to suit all: size Medium will suit a 54-58cm head, size 59-61cm head you should choose Large, and size 62cm and above would need size XL. We do have a size small for juniors available, too (51-54cm).

X-Flow is available in a huge range of sizes to include juniors, ladies, and people with a larger build. See our sizing guide for more information. X-Flow garments are available in various colours to suit your race suit, car livery and sponsors.
