[About Teviron Material] Teviron is a fiber that becomes warmer the colder it gets. It's warm to the touch from the moment you feel it, and there's no cold sensation. It has a higher heat retention rate compared to cotton and wool, and it keeps you warm by trapping body heat inside without letting it escape. Combining warmth and comfort, it's a high-grade thermal fiber that's perfect for everyday life, sports, and all kinds of situations. #Leggings #WarmInnerwear #WinterInnerwear #Women'sInnerwear
