When Chuck Norris chooses an Evo 4G case, this is probably the one he uses. The Seidio Innocase Rugged holster combo is some serious battle armor for your Evo. It's a four-part system, consisting of the Seidio Innocase II Surface for the interior shell, a rugged rubber skin and skeleton protective outer shell, an authentic Seidio Ultimate Screen Guard screen protector, and a locking holster to keep it where you want it to be.
When completely assembled, not a bit of your Evo 4G is exposed. Even the ports and controls are covered by the rubber skin, yet easy to open flaps give quick access to ports and the case is designed so that all the buttons and controls work without removing the rubber. Of course, with everything covered up tight you won't have access to the kickstand, but if you are out and about in a place where you need this level of protection -- on the job, doing outdoor activities, or chasing down aliens, it's a fair trade.
When you don't need the extreme protection the Innocase Rugged offers, the rubber skin and skeleton is easily removed, leaving the Innocase Surface to keep your Evo safe from minor bumps and scratches. You can grab the Seidio Innocase Rugged holster combo in the Android Central store for $39.95. Hit the break to see a slew of pictures, and a quick video showing how the kit is assembled.
