The best products are built to solve a problem. And that's exactly how the Electric Stacker Sunglasses became a reality. The problem was finding a pair of sunglasses that not only look good, but are equipped to handle any outdoor adventure you encounter. Each pair starts with a stylish aviator frame that's tough, lightweight and durable. The lens is polarized, impact-resistant, and prepared to resist water, dirt, and just about any other gunk you might encounter on a bike trail. They'll also stay attached to your face throughout thanks to an anti-slip nose and ear grips that are hidden into the frame. And after a long day on the trails or slopes, just remove the eye mask and these bad boys quickly become your everyday sunglasses.
