React Series is an ultra-slim, resilient OtterBox case with DROP+ protection. DROP + is the OtterBox testing protocol that proves every product we make, at a minimum, meets Military Standard – that’s 26 drops from 4 feet. REACT Series’ solid one-piece form is precision designed for your phone and its soft touch edges provide great grip. The case installs easily and also seamlessly slides in and out of backpacks or pockets.
