Limestone Pioneer

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 lime green temples paired with the dark smoke frame create a perfectly steezy contrast. The blue/green gradient lens ties everything together for a sporty yet edgy final pair of premium eyewear.

SUM's mission to create performance quality eyewear with a smooth, fashion forward appearance is really shown in these Pioneer frames. Particularly with the slender arms and flex-hinge that adjusts perfectly to any size head. 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.
