The U21 underwear kit, consisting of a balaclava, top, and pants, is designed and manufactured in compliance with FIA 8856-2018 standards.

The stretch fabric, featuring an innovative 3D weave, provides excellent flame resistance and effective protection against heat transfer.

Each garment incorporates inserts with F7 technology by EE TECH, strategically positioned in specific areas to enhance performance and optimise muscle management. Depending on the level of physical effort, stress, and tension, these inserts support the best functional response, helping achieve maximum performance.

Careful placement of the seams in pressure-free zones ensures superior comfort while driving.

Each garment can be customised with graphics and logos by fireproof printing.
