In celebration of the Miami Heat’s victorious win, Billionaire Boys Club joins forces with Miami’s very own, UNKNWN.  The t-shirts features the familiar branding of Billionaire Boys Club and UNKNWN, accented with the color and design of the Miami Heat emblem.  In addition, the t-shirt is complete with Lebron James’ signature number 6 on the back.  Billionaire Boys Club is the first of five influential collaborators to work with UNKNWN with subsequent releases to come each day this week.   Arriving in perfect time for that summertime aesthetic, The Championship Tee is available now via UNKNWN’s web store.
