Mast SL, Gloss Black

Tifosi Optics designed the Mast SL Sunglasses with rugged durability that's fit for the outdoors. Ideal for trail running, their scratch-resistant lenses offer total UVA and UVB protection as well an optically decentered design to eliminate distortion. The vented design helps each lens increase airflow and prevent fogging. The TR-90 frame is very durable and bendable for long-term comfort, and hydrophilic rubber covers the nose and temple pads for a no-slip fit.
