Adidas Track Jacket Top I am selling this item because my child has outgrown it. I purchased it on this site. Length: 66cm Sleeve Length: 78cm (Measured by hand. There may be some errors.) Size: S, but it fits loosely. A woman who usually wears a size L can wear this with room to spare. I wore a thin down jacket underneath this in the dead of winter. It's long enough to cover the entire rear and kept me warm.
