The Otterbox Defender Series protective case provides effective protection for your smartphone. The ports are sealed against dust, debris and lint, but are still usable. The two-piece shell is made of polycarbonate and snaps around the phone. It is also enclosed in a synthetic rubber cover that cushions shocks. The Defender XT protective case is also compatible with Apple's MagSafe wireless charging system and is a slimmer version of the Classic version. It is smaller, but still offers optimised drop protection. All the elements for robustness and reliability in phone protection are found in this case.
