Here’s how to keep the world’s best optics at their best. Our Storage/Cleaning Bags for Large Eyewear are made of a soft, lens-friendly microfiber material. Cleaning with ordinary cloth can lead to microscopic scratches that add up over time and compromise your vision. Not so with our MICROCLEAR™ technology. Use these bags for eyewear storage and lens cleaning, and keep your razor-sharp optics on the cutting edge.
