Speck Presidio cases feature the IMPACTIUM Shock Barrier. IMPACTIUM is a dynamic shock-suppression material that lines the case and acts as a shock barrier between your phone and the hard outer case. The presidio is military-grade drop tested at 10ft to ensure your phone can survive the hardest falls. Presidio is the slimmest dual-layer case Speck has ever made while improving protection and offering a new scratch resistant finish available in multiple colors.
