Feast your eyes on the mobile mecca of cool sunglasses. Inside this battery-powered, 14-foot van is an endless display of unique sunnies. The founders (and high school sweethearts!) donate a percentage of proceeds to a different charity every day, so you can justify splurging on those oversized shades. Shop brands such as Spec, Mink Pink, and Wildfox, plus an eponymous line of sustainable bamboo frames. Look out for SunsTruck in the city's best summer destinations, like Brooklyn music fests and Coney Island. Check SunsTruck’s website (thesunstruck.com) for its daily location.
