I haven’t worn a coat in about ten years. My comfortable temperature range is extremely narrow, so if I wear a coat, I always end up taking it off on the train—and it just becomes a hassle. Instead, I layer up from the bottom: sole warmers, long socks, short socks, leg warmers, a long T-shirt, a cashmere turtleneck sweater, a vest, a down vest, a jacket, gloves, a muffler, and a pilot hat. This way, I can shed each item little by little—like an insect adjusting its shell—depending on the situation. I usually take off my muffler and hat on the train. After lunch or when I’m drinking, I sometimes end up removing everything except my long T-shirt on my upper body. You might say, “Wouldn’t it be easier to just wear a heavy coat?” Maybe that suggestion comes from a normal person’s perspective, but for me, this system is the most comfortable. By the way, this cap is made in Poland. I rotate both of them, including the Japanese one I posted yesterday. The Polish one is made of leather, so I don’t wash it, which is a bit inconvenient—but I love it.
