Looking for as much protection as you can get for your Blackberry Z10 without adding military-grade bulk as a result? The Blackberry Z10 4-in-1 Case with Holster is your best bet. There are two layers of protection on this shell: an inner gel case and an outer hard shell, neither of which prevent access to all the important functions of your Z10. Just when you thought you had reached the limit of protection, we're throwing in a sturdy rotating holster so you can keep your phone attached to you at all times. This fully removable holster will give you additional carrying options, keeping your pockets empty and your hands completely free!
