To get ready for Opening Day, Chicago Cubs star Kris Bryant hooked up his teammates with a surprise: the newly released Adidas x Reigning Champ collaboration.

As you can see in the photos, he packed up bags of Adidas gear, including the Adidas x RC Ultra BOOST and alphaBOOST, and delivered them to his 2016 World Series Champion teammates.

Reservations for the Adidas x Reigning Champ Ultra BOOST opens April 4, via the the adidas Confirmed app, with select retailers in North America also carrying them.
