When Jennifer Aniston joined pals Courteney Cox and David Arquette for a relaxing holiday in Mexico, she shielded her face from the sun with a OmniPeace olive hat. Jennifer, Courteney and David are long-tim supporters of Omnipeace, a company who supports the Millennium Promise, a non-profit organization whose goal is to end extreme poverty by 2025. OmniPeace’s t-shirts and hats have been spotted on Zac Efron, Casey Affleck, Sienna Miller, Naomi Campbell and more. 25% of all profits go to the Millennium Promise — the T-shirts alone have already raised $112,000 to end poverty.
