evo.com | Zeal Goggles > The Zeal Hangfire Goggles use a spherical polycarbonate lens shaped to match the curve of your eye, cutting down on distortion at the edges of your vision. Observation Deck Technology tilts the lens for a wider field of view, and the Slide Lock System makes swapping lenses a one-handed job between runs. A semi-rimless frame keeps things light without giving up durability.
