A functional innerwear that helps protect you from the cold in winter. Made of cotton milling material that absorbs moisture and generates heat, it is both warm and comfortable to the skin. Thin and comfortable fit, comfortable to wear without feeling cramped. The crew neck type has an easy-to-use design inspired by vintage thermals. We recommend wearing it in a men's style, such as showing off the tight neckline through the knit collar, which is something you don't often find.
