This is a milestone cap. I'm selling it because I no longer use it. The tag display has faded. The size is free size, approximately 56.5-59.5cm. I will ship it folded. The following is a quote from the manufacturer: The milestone original cap series pursues breathability and comfort. "LIGHTING YOUR WAY" is embroidered on the underside of the brim. A wire is incorporated into the brim of the hat, allowing it to retain its shape. When wearing a headlamp, the light can be directed without obstruction by lowering the brim. The overall head shape differs between Westerners and Japanese people, so even with the same head size, there can be a feeling of discomfort when wearing a hat. Westerners: Narrow width, protruding back of the head / Japanese: Wide width, many with flat backs of the head *Many conventional running caps are narrow, and often make Japanese people's faces look larger. Wearing a hat narrower than the cheekbones can make the cheeks appear to stick out, making the whole face look larger. Conversely, if the hat is wider than the cheekbones, the cheeks appear slimmer, and a slimming effect can be expected. The position of the ears differs between Westerners and Japanese people. For the above reasons, a wider brim suitable for Japanese sizes has been adopted, and the depth has been designed to fit well when worn.
