On a hot day, there's no feeling quite like racing toward the water's edge and diving in headfirst — it's exhilarating, refreshing, and liberating. It's also devastating when you realize, post-dive, that you forgot to leave your favorite sunnies back on your beach towel. Yet another pair of perfect shades, lost to the underwater powers that be....Well, next time, let local brand Panda come to your rescue with its eco-friendly line of sunglasses. Started by a group of college friends and initially funded by a successful Kickstarter campaign (they met their fundraising goal in three days!), Panda officially launched earlier this year and is now tucked away in Georgetown's Paper Mill building. Available in five styles, the shades are handcrafted from sustainable bamboo and recycled polycarbonates, which means they're lightweight, durable, and — the best part — they float. There's a feel-good factor, too: For every pair purchased, Panda donates a pair of prescription glasses and an eye exam to a person in need. We're digging the Monroe, with its classic wayfarer styling, and we can imagine D.C. guys looking pretty fly in the Robinson.
