Yamato Michi Light Alpha Vest/Jacket Men / M size Nomad x Black Comes with the original Yamato Michi outer box. This popular item sold out immediately. Unused. Perfect for upcoming mountain climbing. Reference from HP: An active insulation (thermal action wear) that can be worn continuously in late autumn, the remaining snow season, and low-mountain hiking in winter. Polartec Alpha Direct, a lightweight and highly breathable 85g/㎡ insulation material, maintains warmth while allowing the body's heat to escape during activity, and keeps you warm during periods of inactivity, allowing you to continue to move comfortably in the winter mountains. Furthermore, by removing the sleeves, it becomes a vest, which keeps the core of the body, such as the abdomen, from getting cold, and can handle even higher-load activities. For winter hikers.
