OtterBox's Defender case is a tough container that can protect your phone from the elements -- and from drops and dings. The newest application for the case is for the Samsung S4 Active. It comes in either gray and white or black and features port and plug covers for easy access. The case uses multiple tiers of protection, including a polycarbonate inner layer, a silicone outer later, a screen protector to prevent scratches, and a belt-clip holster. Defender cases are available for many smartphones on the market. Pricing for the S4 Active case is $50.
