STM DUX Surface 3

This sleek and rugged case has been designed to complement the Type Cover and Surface Pen while protecting your Microsoft Surface. Our unique, transparent back panel allows the pristine beauty of your device to shine through. Slim and lightweight, yet super protective, the Dux has been tested to meet or exceed U.S. Department of Defense 810G drop tests standards.

NOTE: Keyboard not included.


we believe good enough isn’t good enough

So, we make it a point to go above and beyond—even in the way we test our products. Military standards for drop testing require that a product like Dux be able to maintain all operating functions after plummeting 26 times for a height of 4 feet. We subjected Dux to our own extreme testing at 6.6 feet. It passed. And that calls for the best drop of all…a mic drop.

Clear Back Banner

if you’re looking to make a case all your own, the choice is clear

We use completely transparent materials for our back panel that allow you to customize your device with personal images, scan a tagging barcode, or simply let the beauty of your device shine through. But there’s one more thing we want to make perfectly clear: this stylish case still provides the maximum level of protection for your digital gear.
