FAQ - Frequently Asked Questions
Why do I need T.ESS work underwear?
Whether Premium, Platinum, or Fireshelter, all T.ESS Workwear workwear has one thing in common: It supports the body in maintaining or largely restoring its healthy balance. T.ESS workwear cools or heats up – as needed – and is therefore as useful as, say, ski underwear. We carry clothing for firefighters, police officers, the military, motorsports, and many other industries.
When the body performs heavy work, it sweats. The body's equilibrium must be restored as quickly as possible. Therefore, work underwear that supports this process is recommended. Depending on the work environment, this can help cool or heat the body. Our premium underwear, with its cooling combination of polypropylene, polyamide, and polyester, is particularly suitable for working in warm rooms and during strenuous physical activity, as its fabrics not only lower body temperature, but also dry quickly and minimize odors.
To help warm the body, we recommend Platinum underwear. Primaloft retains heat internally and polyamide wicks sweat away. Furthermore, Platinum clothing prevents fibers from shedding. Both types of work underwear are also characterized by seamless stitching, which ensures a perfect fit.
What does our work underwear do?
As already explained, our special clothing cools, dries, and warms. It also helps minimize odor and perspiration. If you work in cold environments, Platinum underwear is best for you. It feels comfortable against the skin and, thanks to the polyamide, wicks moisture away.
This special workwear prevents the body from cooling down. The Fireshelter line, however, was developed for work in the presence of fire. This is the first workwear manufactured using the seamless sewing method and meets the requirements of firefighters, police, military, and motorsports. With T.ESS Workwear, you can be sure you'll be prepared for whatever comes your way—whether it's heat, cold, or other extreme situations.
