This fashion staple transitioned from being primarily associated with sports, to becoming a symbol of a casual and athletic lifestyle throughout pop culture. Iconic athletes, artists and celebrities popularized tracksuits since the '70s-'80s and they are still very much relevant to this day. NBA Hardwood Classics Track Jackets and Track Pants by Mitchell & Ness are fashioned with 100% polyester tricot for stretchability and comfort, and self-fabric sleeve stripes for a nostalgic touch.
