Rethink high-performance sunglasses for speed and clarity

The SMITH Shift Split MAG sunglasses are engineered to move with you—whether you’re sprinting along sunlit pavement, carving through a mountain bike descent, or chasing a personal best on a gravel road. The split-frame design keeps the field of view unobstructed while maintaining a featherweight feel, so you can focus on the line ahead without distraction. A secure fit helps you stay composed on rough terrain and fast descents, making every ride or run more confident and enjoyable.

Key design and comfort features

• Ultra-light frame with a flatter, split-frame profile that minimizes obstruction and enhances aerodynamics.
• Durable TR90 frame material with TPU components, plus adjustable megol nose pads and non-slip temples for a secure, staying-put fit.
• Interchangeable lenses: installed bright-light ChromaPop lens for vivid contrast and color, plus a secondary clear lens for low-light scenarios.
• ChromaPop lens technology boosts edge definition, contrast and natural color, while coatings resist smudges and moisture for easy cleaning.
• Built on SMITH’s legacy of performance eyewear and helmet innovation, dating back to 1965.
