Seidio’s ACTIVE X Combo contains an ACTIVE X case and ACTIVE X holster. The ACTIVE X case is the perfect companion for an energetic lifestyle. This dual-layer case includes an interior silicone sleeve with grooves for better grip and the arachnid design of the skeleton extends out to protect vulnerable parts of your Apple iPhone 4 such as the corners and sides. The ACTIVE X holster is felt-lined and features a face-in design to protect your device when carried. Use them together when you’re on-the-go and worry more about moving forward and less about your Apple iPhone 4.
