Product Description nano・universe: "Next-generation sustainable outerwear equipped with the heated vest HOTOPIA®" Based on the "short mods coat," one of nano's popular standard outerwear items, this evolved into a detachable inner type. The pattern has been arranged to allow for a wide range of arm movement, including the shoulders and armholes, while maintaining a sharp look. In addition to the clean appearance of VORTEX spun yarn, it also features water repellency and easy care. The use of sustainably manufactured cotton is also unique to MC. The inner vest uses HOTOPIA®, which allows you to adjust the temperature with your smartphone, making it useful in situations where you go out frequently. By using VORTEX spun yarn for the fabric itself, it eliminates fluffiness and creates a clean appearance, and the strength of the yarn makes it resistant to washing and suitable for harsh conditions. The detachable vest also features a fabric heater, a patented HOTOPIA® technology, using silver fibers for added stretch and breathability. It can also be washed. From the way we choose clothes every season, to choosing clothes that can be worn seasonless and loved for a long time. This is one of the three types of outerwear that MC considers sustainable.
