The fireproof Walero Long Johns are by far the most advanced in the industry.
These FIA and SFI approved leggings provide more comfort and protection for the wearer than any other product on the market. Using the same technology developed for NASA astronauts, the base layer of all Walero underwear actively stabilises body temperature of the wearer, regardless of the external climate.
Intelligent microcapsules, which can absorb and release thermal energy, are incorporated into the yarn before it’s woven. These help regulate the wearer’s body temperature at 37°C, by absorbing excess heat and only releasing it back to the wearer if they are below a certain temperature. Walero’s advanced microcapsules ensure the wearer is never too hot or too cold.
Featuring Envirotech+, a non-toxic, medical grade antimicrobial that is 99.9% effective against the majority of common bacteria, viruses and fungal spores, Walero underwear provides exceptional comfort and hygiene without compromises.
