Secure Mounting - Featuring a Patented Dual-Stage Lock that's quick and easy to attach / detach, but secure enough to lift up to 80 kg (yes, it's been tested). It's all in the technique, not in the force. Protective / Impact Resistant: Quad Lock would never suggest throwing your Galaxy off a double-story building, that's just silly. But with a tough, polycarbonate core and impact absorbing TPU edge-to-edge outer shell, you can be confident that your Galaxy will be protected in your everyday activities. Sleek Design: The slim profile and soft touch material make it perfect for everyday use. Simplicity is key in all of our design, no showboating here. Tech Specs: Secure Quad Lock® interface. Composite construction (TPU / PC). Microfiber lining. Impact absorbing shell.
