Pros: Comfortable, Durable, Optimal clarity, No glare, lightweight

The M Frame is one of the best 'active' sunglasses ever. They are very light, the nose piece is crazy comfortable, they hug your face just right, and they stand up to just about anything. I've had these sunglasses the longest (3+ years) through shooting ranges, training, fights, bottom of gear bags, and they're still like the day I purchased them, if not better, and I have yet to replace any of the ear/nose pieces. They Hybrid is an average sized lens, and depending on your face could actually be considered fairly large.
