Thin and lightweight, these sunglasses by Dxtreme are made for men on the go and can be worn for long periods of time without you even noticing. The shades are made of metal and plastic, pared down and thin so they are comfortable, but still strong and durable. The arms are straight with a slight curved taper and a cut out design element next to the Dxtreme logo on the side. The lenses are set in the frame with rivets and are rimless. They are dark to protect your eyes from the sun.
