I purchased this item used, but I'm selling it because I no longer wear it. I wore it for about two seasons, only during the winter. This is the Ekiden Vapor Jacket from the Ekiden Pack model released a few years ago. It's a model in the Komazawa University color scheme and was very popular. As you can see in the first photo, the Nike logo on the chest has a cut. If you don't mind this, please consider purchasing. The size is men's M. *Please refrain from purchasing if you are sensitive to used items stored at home. m(__)m Suguru Osako, Oregon Project, thick-soled, Ekiden, marathon, road race, Vaporfly, Zoom Fly, racing Olympics, Hakone Ekiden, Hakone, running shoes, racing shoes, running, streak, workout, training, track, road, cross country, running, tech, tech fleece, techfreece, windbreaker, jersey, hurricane jacket, Ekiden Pack, ekidenpack, Undercover, Nike Gyakusou, crimson, engine, Aeroswift, Alphafly, running division, gyakusou, acg, NIKE LAB
