The Dynafit Ultra Evo Sunglasses in Storm Blue are Dynafit's lightest performance sunglasses at 31 g, a half rim Category 3 model for trail running, ski mountaineering and fast touring. The half rim frame is what gives the wide unobstructed field of view when you are looking at your feet at speed.

• 31 g: the lightest eyewear Dynafit make, light enough that you stop noticing them on a long run.
• Half rim with 180 degree wrap: nothing sits in the lower field of view, which matters when the ground is technical.
• Category 3 lens: the standard bright sunlight category, suitable for general mountain use unlike a Category 4 glacier lens.
• Ventilated lenses and frame: the Climacool AirVent system moves air across the lens to stop fogging during effort.
• Interchangeable lenses: the switch system lets the lens be changed for different conditions.
• Grippy contact points: rubber temple tips and a silicone nose pad hold position when you sweat.
• Case included: a foldable case and microbag come in the box, and the glasses are made in Italy.
