A white undershirt beneath a white shirt often becomes more visible, because it creates a strong contrast against the skin. Covert Underwear works differently: the skin-tone shade visually blends with the body, while the laser-cut edges minimise the visibility of sleeves, neckline and hems. At the same time, it acts as a practical barrier between the body and the shirt — helping absorb perspiration and protect premium shirts from deodorant marks, yellowing and everyday wear.

For this type of undershirt, it is usually best to choose one size smaller than your regular T-shirt size. For example, if you normally wear size L, size M will most likely work better. The undershirt should fit very close to the body so that it does not shift, bunch up or create visible lines under a shirt. Thanks to the soft Mako cotton, however, it should still feel comfortable rather than restrictive.

It is especially useful under white business shirts, light-coloured shirts, summer linen shirts and shirts made from finer or slightly transparent fabrics. It is not meant to be seen — its role is to improve comfort, keep the shirt cleaner for longer and preserve a sharp appearance without distracting outlines from the base layer.

Wash according to the care label, preferably inside out and without harsh tumble drying. Fine cotton retains its shape and comfort best with gentle washing and natural drying. Avoid bleach and unnecessarily high temperatures.
