The Tech21 Promise

Protection Made Intelligent.
All tech21 products offer advanced impact protection that's rigorously tested to work harmoniously with your device. Like the technology they're designed to protect, our products use the latest science, ingenious design and unbeatable user-friendliness to make this possible.

Impact Protection. Evolved.
Our constant search to do things better has resulted in FlexShock™, an ultra efficient material that absorbs and dissipates impact force, stopping that force from passing into your device - without impacting functionality. Less efficient materials let the force pass straight through to your phone giving minimal protection and can even negatively affect phone performance. FlexShock™ also enables tech21 cases to be thinner and lighter, but still give the best possible protection and can even be colour matched to any device or style trend.

Tested to the limit.
At tech21 all our products go through a series of rigorous tests to ensure they work in harmony with your device. This means unhindered signal quality, such as Wi-Fi or Bluetooth; easy access to all buttons and ports and core functionality such as camera, acoustics and sensors will work as intended with the case on or off.
