The TPU (Thermoplastic Polyurethane) case is a nice compromise between the flexibility of the soft silicone skin, and the stronger form factor of the harder crystal and polycarbonate cases. The TPU material is highly resistant to scratches and fingermarks. It is pliable, yet resistant to tearing, making it good-looking and long-lasting alternative to other materials.
The case has cutouts for the stand on the back panel, the connectors, and camera lens and flash. There are also cutouts on the back to provide additional ventilation and cooling for the phone. The power and volume control buttons are covered by a thinner section, allowing them to be easily manipulated and ensuring that dust and moisture connect enter through the controls.
