Men's T-shirt Covert Are you looking for a sweatband T-shirt that is invisible under your clothes? Then this T-shirt from the Czech brand Covert is the right choice! A men's T-shirt under a shirt is intended for those who have become accustomed to wearing a T-shirt under their shirts instead of a tank top. Because a white T-shirt under a white or light shirt shows through, especially in the area of the sleeves, we replaced the white color with a nude color. The perfect "invisibility" of the T-shirt is also guaranteed by the processing of the material. The T-shirt has absolutely flat thin edges that do not show even under the thinnest shirt material. It perfectly absorbs sweat and protects against the formation of wet stains on the shirt. As far as washing is concerned - our recommendation is to wash them at a maximum of 60°C and dry them in the dryer at a low temperature, otherwise it may happen that the T-shirt can no longer be worn.
