Your sunglasses felt great during the first two miles of your trail run, but the long 900 foot climb left them slick with sweat and put a bit of fog along the top of the lenses. To make matters worse, the long descent that followed was littered with long sections of rock sandwiched between sections of loose dirt, which kept your eyes directed down towards the trail, and made your sunglasses slip down your nose between each step. Obscured vision is a tough pull to swallow, but you'll be ready for race day when you wear the Julbo Breeze Sunglasses with Spectron 3 CF lenses. The lighweight frame is specifically designed to hang tight to your face thanks to fully adjustable temples and a 3D Fit nose pad that can be adapted to match the shape of your nose for a solid hold, even when you start to work up a sweat. The Breeze's lightweight construction offers a comfortable fit and reduces fatigue around the ears, while a full venting frame allows a constant supply of air to pass along the sides and bottoms of the lenses, ensuring minimal fogging when you push it to the top of another steep climb.
