Tifosi's Crit Interchangeable Sunglasses deliver clear views and reliable protection when you're five miles into an eight mile trail run or pedaling up a steep series of switchbacks on your mountain bike. The vented design lets air circulate through as you move to keep the lenses clear of fog and the hydrophilic coating makes moisture from sweat and rain roll off the lenses to prevent those pesky little dry water marks from clouding your vision. The rubber ear and nose pads can be adjusted for a precise and comfortable fit. Each option comes with additional lenses (see size chart for additional info on lens options) to adapt to changing light conditions and lens changes are made easy through Tifosi's lens anchor system.
