Wear Your Jersey. Show Your Pride.

MLB fans, take note—you’re fully excused to wear your team's jersey to work today.

Majestic Athletic’s Jersey Day is a national celebration of baseball pride where all 30 MLB® clubs and their fans join together to show their passion by wearing their authentic Cool Base Jersey—15 clubs were assigned their Jersey Day on May 22, and the other 15 on May 29. 

Fierce Competition

At its core, Jersey Day is about fans showing their team pride.

But that line between pride and competition—it’s a thin one. Jersey Day taps into this fervor. Fans are encouraged to prove they are the “loudest and proudest” by using their club’s hashtag to fuel real-time standings at

In addition to robust digital and social activation, Jersey Day is supported by POP marketing in stores and stadiums, consumer promotions, a jersey influencer program (see: Flo Rida), and club integration that includes in-stadium assets, promotions and street teams.

The Brand Behind the Battle

Jersey Day is the brainchild of GMR client Majestic Athletic, the exclusive creator of MLB’s on-field uniforms, Authentic Collection apparel, replica jerseys, and a variety of additional fan apparel. Majestic made its on-field debut in 1982 and has had a growing presence in baseball ever since.

“Jersey Day is a great opportunity for fans to show support for their favorite MLB club," said Reece Nanfito, Director of Marketing for Majestic.

"We have developed this promotion involving MLB, the 30 clubs, and all major retailers and e-comm partners to celebrate their passion for baseball, wherever they are on that date. And this year, it fit perfectly into our launch of the new Majestic Cool Base jersey."

GMR’s Role

Majestic tapped GMR for a broad range of digital, creative and tactical support for Jersey Day 2015. GMR was responsible for the Majestic Jersey Day microsite, social media campaign, consumer promotions, influencer outreach, in-stadium activations, and all creative across digital, print, in-stadium and retail.

"GMR did an excellent job planning a national integrated marketing program to promote the event and drive jersey sales," said Nanfito. "We are very pleased with the results, and look forward to this becoming an anchor event each season."
