A Revolution in design that reverberates with your lifestyle. This particularly lightweight case is exceptionally rugged, courtesy of a proprietary ?structural truss? x-frame chassis engineered to resist twisting and bending, and an exclusive drop shock corners design that dissipates energy to withstand extreme bumps and drops. Rev has also been drop-tested beyond the industry?s mil-spec standards to deliver the ultimate in high impact protection. The unparalleled Element Case 10/65 testing subjected a single case and phone to being dropped from a height of 10 feet 65 consecutive times, as well as being tossed from a moving vehicle at 65 mph.
