Here reviewing my See concepts Brown D Tortoise Sunglasses. Not the most expensive pairs of sunglasses I own but by far the best. They are about 80-70 bucks. It's kind of this like somewhat flimsical plastic but it fits perfectly Rayban's move around in your face a little bit. These stay put. Most comfortable sunglasses ever. The lenses are great and let's be real about it. The appearance is pretty pretty awesome also.
