This shirt? It’s more than just a shirt. It’s a binding agreement that makes you an official founding member of Robert and Susan Downey’s new philanthropic initiative, Random Act Funding. Each year, RAF will provide grants to different nonprofits, helping to empower them and fuel their world-changing work. The first beneficiaries are Make-A-Wish, the Motion Picture & Television Fund and the Anti-Recidivism Coalition—remarkable organizations that use their heroic efforts to make the world a better place. So join forces with Robert, Susan, RAF and Omaze, and get a sweet shirt out of the deal, too.
