Thermal underwear is a close-fitting garment (top, leggings, trousers or full set) worn next to the skin, under other clothing, to retain heat and draw sweat away.
What it is for
Used as everyday workwear, where durability and freedom of movement are needed.
How to use it
Wear directly on the skin, under work clothing, choosing a close-fitting size that is not tight. Use it for outdoor work or in cold environments, combined with outer layers that protect against wind and rain. Wash as indicated on the label, at a moderate temperature and without fabric softener, which reduces the fabric's breathability.
