If you are a fan of rugged yet slim cases, definitely take a look at the Urban Armor Gear case for the Galaxy S4. The case consists of a shock-absorbing inner rubber layer, and a rigid plastic mid-shell. Each corner has been reinforced with thick rubber to protect your phone from those deadly corner drops. UAG offers the case in four colors and includes a screen protector. At $35, this case contends with the Otterbox Defender and SPIGEN SGP Slim Armor.
