Review: Smith Bobcat Sunglasses | The Loam Wolf。Chromopop opal mirror lense. It’s a category 3 lense, (partial sun) and I have sensitive eyes so needing a bit darker of a lense. The side arms were switched out with a different pair of bobcats (pictured last, not for sale) Leaving these with colors that no one else will have! -comes with the case, an extra clear lense (think mtb at dusk), a lense cleaner/protective sleeve, and sticker. These sunglasses are great for outdoor adventure as they have good coverage, airflow, and stay on your face. A little bit about the technology (taken from Smith website): ChromaPop™ lenses enhance contrast and natural color to make the details pop Interchangeable lenses Fit / Integration Small to medium fit, large coverage 5-base lens curvature Slight wraparound fit Megol temples and nose pads provide non-slip grip so glasses stay put Two-position adjustable Megol nose pads Evolve™ bio-based frame material is lightweight and durable AutoLock hinges hold frames open for easy one-hand on and off Strategic venting increases airflow for reduced fogging and maximum clarity
