This is the first collaboration item with the outdoor lifestyle brand 〈YDOT〉, which was established in 1983 and is currently based in Denmark while conducting its creations in Japan. The base model follows the design of the first model created in 1988, updated with a modern twist to become a classic model. It features ultra-lightweight materials, making it convenient for carrying and storage with its packable design. In addition to its high insulation due to the ample amount of down, it boasts functional features such as pockets with hand warmers, a detachable three-dimensional hood, and large-capacity inner pockets. For this exclusive edition, black, which is not available in this season's inline collection, has been chosen, and the length has been slightly shortened for a sleek and easy-to-wear fit. The design and button placement have also been readjusted to match the length. The down is filled with Crystal Down®, which is carefully selected high-quality, voluminous European down.
