Every year, marathon runners cross the finish line at Copley Square and claim the adidas Boston Marathon Celebration Jacket as a badge of honor. This year, the iconic jacket is designed with the planet in mind. A nature-inspired print honors the Earth while you run it. From your warm up to your cool down, the body-mapped design cools and wicks sweat in key areas, and it has plenty of pockets to store your phone and gels. Don't forget to note your personal time and bib number on the inside label as a lasting memory.
