We know how important your phone is to you, so it’s important to keep it safe from life’s unexpected mishaps, however they happen. Our in-house design team are always looking for ways to do things better. Materials that were once state-of-the-art are now no longer fit for purpose. This constant evolution has resulted in FlexShock™, the world’s most advanced impact protection material – exclusive to tech21.

FlexShock™ is ultra efficient, absorbing and dissipating impact force and stopping that force from passing into your device, whilst at the same time ensuring the device continues to work as intended. Less efficient materials let the force pass straight through to your phone giving minimal protection, increasing the likelihood of damage, and can even negatively affect phone performance.FlexShock™ is strong and flexible so you don’t need much of it to provide amazing protection. tech21 cases can therefore be up to 30% thinner and 60% lighter than others, but still give the best possible protection. 

FlexShock™ can also be made in any color, ensuring tech21 cases can be color matched to any device, or designed to suit the latest trends.

All tech21 products offer advanced impact protection that’s rigorously tested to work harmoniously with your device, meaning unhindered signal quality and full access to all ports and functions. Like the technology they’re designed to protect, our products use the latest science, ingenious design and unbeatable user-friendliness to make this possible.

One year on in our journey to creating the worlds best impact materials, we are the first business ever to have a partnership and lab space at the NPL (National Physical Laboratory) in London. To improve, we need to know how we’re performing. So, we’ve invested in a new R&D facility at the NPL. NPL is the UK’s National Measurement Institute, a globally recognized leader in its field. It’s also the UK’s largest applied physics organization.

Working in partnership, we’ve built cutting edge equipment, a unique testing methodology, and formed a team of highly skilled scientists. This means more advanced testing. More accurate results. And an unbeatable range of drop protection products that you can trust. NPL is home to over 500 full time scientists and technicians, providing an incredibly powerful mix of skills and experience to draw on. 

This means tech21 can innovate faster and create products that are difficult to beat. Through this partnership with the NPL we were able to innovate and create unique products for the iPhone 7 launch that set us aside form our competitors and made us stand out in the impact protection market.


Lack of protection and poor durability are common problems in the fashion case category. By using FlexShock™ material, Evo Elite offers 350% more effective protection than the marketing leading fashion case, yet is still incredibly thin and lightweight. An advanced application technique gives Evo Elite a smooth, durable finish that can be Pantone matched to any colour.


Evo Check is our best-selling product. This year we’ve kept the same popular design but updated the way it protects your phone. Featuring an all new 3-layer impact absorption system, Evo Check for iPhone 7 / 7 Plus offers you 50% more protection than the previous generation. This is thanks to a hard dispersion layer which works seamlessly with FlexShock™ to absorb and dissipate impact force, stopping it from passing into your phone.


Thanks to FlexShock™ and the all new 3-layer impact protection system, Evo Wallet offers 50% more protection than previous versions. And because FlexShock™ is so efficient, it’s still thin and lightweight. We’ve also added a second lining in the folio cover which keeps your cards easily accessible, but hidden from prying eyes. Finally, and most significantly, we gave Evo Wallet a detachable folio cover. This means when you need the extra storage, you’ve got it. When you don’t, just use the quick release tabs and remove it.


Our Evo Tactical Extreme Edition case was designed to offer maximum protection for those of us who spend our time in harsh, unforgiving environments. For iPhone 7, we’ve slimmed it down so it feels more comfortable in your hand and narrowed the front frame for maximum touchscreen interaction – without compromising impact protection. Overall, it’s the most effective rugged case available.
