The Marc Jacobs x K-Way waterproof jacket, which we highlighted here about a month ago, now has an official ad. The video features an extraterrestrial-type figure clad in all green Lycra and rocking the fresh jacket all over the streets of New York. This jacket is already a must-have for the fashionably inclined and is available now at Marc Jacobs stores globally. The music in the video is by Dirty Art Club.
