The arms of these cool shades have an extra panel on the bottom that adds to their thickness and strength. Made by Oxigen for men, these sunglasses are designed to fit and stay on in any circumstance. The frame is solid plastic with a durable, yet lightweight, composition. The arms come straight off the face and have a slight inward curve throughout. The Oxigen logo is seen on a silver field on the side. The lenses are dark with a rounded look and offer excellent UV protection.
