If you're already familiar with the Swingarm's classic looks and you live an active lifestyle, then today is your lucky day. As part of its S-Line, Electric upgraded the Swingarm with high-performance materials and features to create the Swingarm S Sunglasses. Now you can skate, hike, or just chill in greater comfort without sacrificing style. Electric removed all unnecessary material from the frame while reinforcing critical structural areas to make these shades stronger, yet also lighter. Plasticam hinges also boost strength while shaving weight for greater comfort and durability. Performance Grip nose and temple pads keep your sunglasses in place even when you're sweating hard and moving fast. When you want style that performs, reach for the Swingarm S.
