These X-Loop color-mirror-lens men's sports aviators are classic aviator shades with a modern twist. The way that aviators looked in the past needed a definite update. The lenses on these shades are as big as what you would find with the older versions. There's also a double metal bridge between the two lenses. Although this small design element might not make that much of a difference, it's important for maintaining the structural integrity of the shades. Some varieties of these sunglasses have a darker tint than others, but they all provide a considerable degree of protection from the sunlight.
