Protective cases

Together with the team of GEAR4 we’ve created an extensive range of stylish phones cases that offer the ultimate in impact protection using D3O’s® unique patented technology.


D3O® is a ground breaking impact protection solutions company that licenses a range of unique patented smart materials. It is also the name of the patented protective material that combines enhanced chemistry with product engineering to produce high performance shock absorption and impact protection. The material flows freely when moved slowly in its raw state, but on shock, locks together to absorb and disperse energy, before returning to its flexible state.

Design highlight

D3O® is integrated into all GEAR4 phone cases, designed specifically for the iPhone and Samsung phones. GEAR4 is also the first case brand to use injectable D3O® delivering more impact protection per cubic millimeter. This smart collection of ultra-slim, ultra-stylish, ultra-protective cases will surely make an impact!


Gear4 is the Number 1 phone case brand in the UK with a rapidly growing market share in North America.
