Touted to be the “world’s first bike helmet with retractable lens”, it is a refreshing idea, although whether it really is the first of its kind in the market remains to be seen. Anyone wants to dispute that particular claim? The Dux Helmet basically relies on a simple sliding button in order to drop a lens over your eyes, and when there is no need for the shades, just pull it up out of the way. If you want to change the color of the lens, just press a quick-release action and the lens can be removed in a jiffy. It won’t come cheap though, as the Dux Helmet with a single gray lens will cost you$179, while other lenses in different tints will range from $30 to $35.
