The JAPAN EDITION collection was developed by a Japanese design team to suit Japan's climate and trends. This vest, based on the '90s Windy Ridge Jacket, known for its large hip pockets, features updated materials. The padding is made with the advanced "Photoelectron(R) Down" material, which utilizes the far-infrared effect generated by the wearer's own body heat. This prevents overheating while maintaining natural warmth. Furthermore, the combination of this material with nylon ripstop, made from a high-density weave of ultra-fine nylon threads, results in an extremely lightweight garment.
