Elvex Xenon grey anti-fog safety glasses represent our most lightweight design. They are so lightweight that it is easy to forget that you have them on (weight is only 0.8 oz or 22 grams). Xenon fits smaller faces and female faces very well. Since this design also is quite stylish and comfortable, we know that we have a winner on our hands. In addition to its good looks Xenon offers a soft rubber nose bridge and colorful rubber inserts on the temples.
