Lantage Thermonics Innerwear Cold and IFBT Top, Heat-Generating, Temperature-Regulating, Sweat-Relieving, Sports-Specific (L, Black), Weather,

[Temperature regulation and antibacterial/odor-resistant technology from Swiss company HeiQ] The fabric is processed with a special polymer made using HeiQ Smart Temp technology from Switzerland. It is a moisture-functional polymer that quickly absorbs and releases moisture. When our body temperature rises, we sweat, and as the sweat evaporates, our body temperature is lowered by the evaporative cooling effect. This polymer supports this mechanism. When body temperature rises, it releases moisture, absorbing heat and lowering body temperature. On the other hand, when body temperature is low, it traps and retains moisture within the polymer. It prevents heat from escaping, preventing the body from cooling down due to evaporative cooling. It also has antibacterial and deodorizing properties thanks to HeiQ Pure TAG technology. [Moisture-functional polymer works!] When skin is cold, it retains moisture (= prevents heat from escaping) When skin is hot, it releases moisture (= heat is lost) Controls body temperature to maintain a constant level! [Soft and comfortable fleece! Thick, skin-friendly innerwear] The fleece material makes you feel warm just by putting your legs through it. Even if you can't wear synthetic innerwear because it dries out your skin, this is a great choice. [Basic crew neck for excellent versatility] The crew neck design makes it easy to match with any style. It can be worn as an inner layer or as a lounging piece indoors. [Unisex] Can be used by both men and women.
