What difference does it make in actual wear when a coat's pocket lining is brushed?

In winter outerwear, the place your hands touch first is the inside of the pockets. INSILENCE's 클래식 맥시 코트 BLACK features a brushed lining for the pockets instead of regular fabric^[1].

The difference is noticeable the moment you slip your hands in. The thin, slippery lining often used in standard outerwear pockets feels chilly as soon as you put your hands in, but brushed fabric—with raised surface fibers—traps warm air between the fibers, easing the initial cold contact. Even on days when you forget your gloves, simply walking with your hands buried deep in your pockets helps keep warmth reaching your fingertips.
