Protective case for mobile devices with an integrated multi-layered construction to provide enhanced protection while minimizing bulkiness and weight. The case has a front face, back face, perimeter, and corners. The multi-layered construction involves molding three distinct layers together in an integrated construct. The layers are the inner layer, middle layer, and outer layer. The inner layer directly contacts and conforms to the mobile device. The outer layer provides impact resistance. The middle layer provides shock absorption.

A mobile phone case design that improves user experience by providing better grip and protection without adding bulk. The case has separate buffer sections for the top and bottom parts of the phone, connected by a narrow middle section for gripping. This allows better handholding compared to a single wide buffer around the whole case. The narrow middle section prevents the case from being too thick and heavy while still protecting the phone's vulnerable areas like camera, charging port, and mic. The case also has features like sound transmission holes, thermochromic layers, and limiting plates to enhance functionality and durability.
