Walero Temperature Regulating baselayers are perfect for both motor racing and Rally use, especially in hot or cold conditions and the brand produces by far the most advanced fireproof underwear for motorsport available on the market.


Walero’s FIA and SFI approved race and rally base layers are softer, more comfortable and more protective than most other base layers on the market. Whilst other products offer sweat and cooling benefits, a lot have a compromised solution for this benefit. Walero knows that you need more which is why all of their next to skin base layers use the same technology developed for NASA astronauts, which actively stabilises body temperature, no matter how much heat a driver faces.


Incorporating super intelligent microcapsules into the yarn before it's woven is the major benefit of Walero. These microcapsules absorb heat energy and gives it back to you below a certain temperature; helping stabilise your body at 37°C degrees and reducing sweat by up to 33%. This thermoregulating technology means that no matter how intense your race conditions, you'll never feel too hot or too cold.


Walero also has added Fantex, which is a non-toxic, hospital grade antimicrobial that is 99.999% effective against many common bacteria, fungal spores and viruses. This means that it will help keep you feeling fresher for longer and it won’t pong of sweat – making success smell so much sweeter!


This underwear REALLY is worth the money.

Active temperature control       

Developed by NASA for off-world applications, Outlast® technology actively regulates your body temperature despite changes in your environment, keeping you cool when the temperature rises or lessening the chill when it falls. This thermo-regulating know-how has been proven to effectively reduce perspiration by up to 33%.

Tailored for comfort       

Walero race underwear has been tailored for a superior fit with flat-lock seams and super-soft fabric to ensure maximum ease of movement and palpable comfort from start to finish.

Freshness beyond the finish line                

Treated with Fantex ™, Walero next-to-skin base layers keep you fresher for longer meaning no more smelly kit bags either! This cutting-edge, hospital-grade antimicrobial is 99.999% effective against many common bacteria as well as many fungal spores and viruses, as well as being non-toxic and eco-friendly.

Protection when needed

Ready to face the unexpected, Walero base layers are quality-assured and have been tested and approved to FIA 8856-2000 and SFI 3.3, which means they are fully flame-retardant and fully approved for racing worldwide.
