The Pioneer is a large frame with full field-of-vision coverage and enhanced sun protection. A unisex style that is universally sought after for its action sports ready features and dope style. The glossy black frame/temple paired with the gold gradient lens create an everyday use color-way that is also fully stylish.
SUM's mission to create performance quality eyewear with a smooth, fashion forward appearance is really shown in these Pioneer frames.

This feature was designed for people to be able to wear the sunglasses without a headache and the end of a long day of use.
