A strong piece of high-tech: The Gear4 Wembley Flip Case is equipped with D3O. This high-tech material offers unparalleled protection against drops and is used by Olympic ski teams as well as the military. Gear4 equips its cases with D3O to provide your smartphone with the best protection against drops, impacts, and shocks. Gear4 is the first case manufacturer to use the latest generation of D3O, which extracts more protection from every single cubic millimeter than comparable materials. This allows Gear4 to deliver cases that are ultimately slim, elegant, and protective - making a crucial difference for you and your smartphone, whether during major events or minor accidents.
