The latest item made available for customization at the Nike Studio Harajuku is this AW77 hoodie. Based on the “Ekiden” hoodie (named for the famous The Tokyo-Hakone collegiate relay marathon), the piece packs in both customizable style and running-specific functionality – like a hidden zip pocket in the hem, and a system for threading headphones through the hood. The iD-able areas include the back of the body and the chest; in addition the standard embroidery, chenille Varsity-type letters are an option. Available in both mens and womens sizes now at the Nike iD Studio at Nike’s Harajuku flagship. Check out images of the sweatshirts after the jump.
