adidas Originals Firebird Track Top Black WhiteFive years before adidas introduced their three-leafed Trefoil logo in 1972, the brand's first ever run of performance tracksuits were shipped to stores. For the last 45 years, variations like the Firebird, Beckenbauer, Hooded Flock and Superstar have made adidas' tracksuits one of the most iconic fashion statements of all-time. From hip hop to sports to entertainment, the two piece suits have left an imprint that will likely hold strong for another 45 years.

In November 2010, adi decided to pay homage to the iconic gear by celebrating the first ever National Tracksuit Day. Fans were urged to dig into their closets and pull out their favorite tracksuit for a nationwide salute to stripes. The unofficially official holiday was a rousing success and is being celebrated for the third time today, a day before the birthday of brand founder Adi Dassler.

This year, several adidas Basketball athletes joined the fun, sharing photos of themselves wearing striped tracksuits on Twitter and Instagram. Players like Ricky Rubio, Charles Jenkins, Harrison Barnes, Serge Ibaka, Perry Jones III, Andre Drummond, Quincy Pondexter, Nolan Smith, Nicolas Batum and Damian Lillard were all decked out in stripes today.

The National Tracksuit Day celebration doesn't have to end today. You can shop various styles for men and women today at adidas.com.
