Magna-Seal™ Series: Positive and negative ions mix with molten aluminum to make one of the most versatile metal sunglasses ever invented. Through patent Magna-Seal™ technology, gaskets can be placed or removed simply by sliding the aluminum gasket on and off the frame. Dimensional gaskets lock to the frame through magnetic attraction. Ultra Foam™ coats each gasket providing wind protection in all directions when desired. A mini-elastic strap attaches to the frame through T-Peg™ docking converting the frame into a functional goggle. Remove the gasket and you have a great pair of sunglasses in any casual setting.
