Comfort meets performance for people with smaller faces in the Zeal Emerge Sunglasses. The ultralight Z Resin frame won't weigh you down on long rides or runs, and it's made from plant based materials to reduce the use of petroleum based plastics. The e llume lens is also made from plant based materials, but don't think for a second that Zeal sacrificed optical quality for eco friendliness. It meets the highest standards of clarity, plus it's polarized to reduce glare and features hydrophobic and oleophobic coatings to repel whatever gets in your way. Customized airflow channels provide micro circulation that cools and prevents fogging without irritating the eyes so you can keep going all day long.
