Smith Shift Split Mag Cycling Sunglasses Review
Smith delivers with their iconic sporty look, ideal for biking, running and warm days on the slopes. The Smith Shift Split Mag Sunglasses deliver an impressive blend of style, functionality, and durability. Designed with outdoor athletes in mind, these sunglasses cater specifically to those who demand performance.
Performance & Features Fit & Comfort

One of the standout features of the Shift Split Mag is their iconic, sleek design, which looks great whether you’re on the trails, cycling, or just enjoying a casual day out. I found the lightweight frame ensures a snug, comfortable fit without causing pressure points, even after hours of wear. The adjustable nosepiece and secure grip on the arms make these sunglasses stable, staying put through those bumpy downhill rides. These glasses are also compatible with Smith helmets ensuring a fuss-free ride.
Lens Options & Technology

The lens quality is where the Smith Shift Split Mag really shines. I went with the Red Mirror Lens – that comes with an additional clear lens – and I couldn’t be happier. Equipped with photochromic technology, the lens seamlessly adapts to changing light conditions, offering the perfect amount of tint whether you’re in bright sunlight or shaded areas. The signature ChromaPop technology enhances contrast and natural color for a clearer view.

Magnetic Lens Change System

The “Mag” part of the name refers to the innovative magnetic lens changing system… or rather arm changing system? The arms simply pop off the current lens and pop on to the new one.

Simply add the nose piece and you’re done. No more mucking up the entire lens trying to jam it into the frame. This is perfect for those of us who head out before sunrise or get back after sunset and want a clear frame option.
Durability
The Shift Split Mags are constructed from high impact resistant TR90 nylon and seemed quite durable upon inspection. The hinge design which clips on and off during lens interchanges also seamed sturdy and capable of many swaps. I’m excited to push these frames to the limit.
