FIRESHELTER is the first flame-retardant seamless underwear in this material mix to boast all the relevant certifications. It also boasts outstanding test results. The results of the air permeability, moisture management, absorption rate, absorption capacity, and the results of the skin model test prove: Our functional underwear is always a step ahead of other products. In addition to its certified flame retardancy, FIRESHELTER impresses with the same features as the rest of TESS's seamless underwear: flat seams, comfortable cuffs, fast drying, and minimized thermal bridges. Both the flame-resistant and protective workwear feel soft and very comfortable against the skin, keeping it dry and maintaining the wearer's full performance, whether they are a firefighter, police officer, oil rig worker, or competitive racing driver.

You know: You can rely 100% on FIRESHELTER.
