This is a Nike Chelsea FC 2017-2018 season zip-up track jacket. The vibrant blue color makes for a striking sporty design. It wasn't sold in Japan at the time, and I purchased it directly from the official website. I think it's a rare model that's hard to find now. - Brand: Authentic Nike (Product number: 905477) - Team: Chelsea FC - Color: Blue - Size: Men's L (Tag says M, but it's equivalent to a Japanese L due to US sizing) Length 68cm, Width 55cm - Design: Zip-up jacket - Condition: Worn as casual wear. There are no noticeable stains, and it's in overall good condition. *As shown in the last image, there is some slight pilling near the side pocket. Please understand that this is a vintage item and purchase accordingly!
