As the first goggle on their line to feature the Observation Deck Technology (ODT), the Zeal Beacon Goggles are the technical and performance first goggles that you’ve been looking to upgrade into. ODT puts the bottom of the goggle frame closer to the face for improved vertical peripheral, and teaming with the Zeal polarized technology, offering superior protection against sun rays. The Beacons are over the glasses compatible and have an upper and lower vent system.
