The hissing of your buddy who overtakes you through the rock garden is basically just an invitation to chase. With these Smith Attack MTB sunglasses, you'll be happy to oblige. The lenses with maximum coverage utilize ChromaPop technology to enhance details and colors, allowing you to focus on the trail ahead. The non-slip temples and adjustable nose pads ensure that the glasses fit comfortably over any bumps and wet roots. When you finally catch up and head back to the shuttle, you can quickly switch between the included lenses for bright and low light with Smith's MAG interchangeable system.
