Eminem, who contributed music to the Southpaw soundtrack, and Shady Records collaborated with boxing brand Title for official merchandise for the film starring Jake Gyllenhaal.

The collection will include boxing-inspired T-shirts and hoodies that pull direct references from the film and Eminem's music contributions to Southpaw's soundtrack. There's also authentic boxing gloves, in case you're a real fighter. 

Keeping in theme with the film and sport, the lookbook shot by Eminem's photographer, Jeremy Deputat, features a few graduates from Detroit's Downtown Boxing Gym—in action—at their old stomping grounds. 

The collection is available online now. Additionally, Shady Records, Title, and Marshall Mathers Foundation are holding an online fundraiser to benefit the Downtown Boxing Gym charity organization. A number of boxing gloves signed by Eminem himself will be given to 10 winners. One winner will also be given the ultimate prize—a handwritten response to a "Stan" fan letter from the rapper (!!). All you have to do is sign up for the email list to find out when the contest goes live on ShadyRecords.com next week.
