Revo lenses make these Khan bulk sunglasses not just a fashion statement, but an excellent tool for enjoying the outdoors in all its glory. Revo lenses provide excellent visual clarity from all angles. These sunglasses for men bear the classic styling of aviators: full metal rims that wrap around the lenses, a pair of silicon nose pads that can be adjusted to customize fit and double bars at the nose. However, this reengineered version features thicker endpieces that continue on to the arms. The Khan logo is stamped on a metal strip at the temples. The arms are made of black plastic. The lenses come in a variety of two-toned gradient lenses.
