    Be confident and carefree

    Even if you’re really careful, the chances are you’re going to drop your phone at least once. So keep it safe from damage with the Evo Check case. It uses FlexShock material to absorb impact and save your phone from bumps and knocks. And it’s made of three layers that’ll protect your phone from drops of up to three metres. So you can relax and get on with your day.

    So thin you’ll forget it’s there

    Evo Check offers premium protection – but that doesn't mean it'll bulk up your phone. FlexShock is ultra efficient, so a little goes a long way. That’s why Evo Check is just 1.6mm thick. And it's so lightweight you'll forget it's there at all.

    Use your phone the way you want

    No need to remove your case while you're charging. Evo Check has been tested to make sure it doesn't interfere with your signal or wireless charging. And it’s designed to give you easy access to all your ports and buttons. So you can use your phone the way it was meant to be used.

    Get lifetime cover

    Your phone goes through a lot. So you need a case you know can rely on. Evo Check comes with a limited lifetime guarantee, so if it develops a fault during normal use then they'll replace it for free. Find out more.
