The Dragon DXS is a smaller version of the DX Goggles. They have the same great qualities and price as the DX’s. Well made, interchangeable lenses and will last a long time. We like the replaceable straps and lenses. We also like that these goggles have been around for a while so you can get almost any lens you want for any condition. The goggles aren’t the best with anti-foging but do a great job as long as you take good care of the lenses. Other than that they are a great goggle for the price.
