The best of adidas past, remastered for the present. The SST track jacket was originally designed for tennis court warm-ups. This version is made of sleek tricot fabric, which is smooth and slightly shiny on the outside, and built with just a bit of stretch for comfortable movement. The Adicolor collection inspired by adidas heritage, Adicolor is authentic but modern. Iconic details - 3-stripes down the sleeves and a Trefoil logo detail on the front show adidas pride. Classic fabric, sporty tricot is smooth and slightly shiny with a little stretch.
