See All The Grips

180° Wrist Rotation

The quick-rotate wrist can spin 180°, making the arm suitable for a wide range of tasks.  Both Small and Large size wrists are available.


MagSwap™ Removable Covers

Switch up your style to match your mood – with over 50 swappable magnetic covers, the Hero Arm is an extension of your personality. Every Hero Arm includes one set of free covers. Choose from a wide range of styles including Star Wars BB-8 and R2-D2, Marvel Iron Man and Black Panther, Disney Frozen, and many more.

Or, wear the arm without covers for extra breathability, and our VentTech™ liner and frame design will help keep your arm cool.


BOA™ Fit Adjustment

Your limb expands & contracts throughout the day, and your Hero Arm can too! Thanks to the BOA™ fit adjustment dial, you can tighten or loosen the frame and find your perfect fit.


Flexible VentTech™ Liner

Using our FlexPrint™ process, the Hero Arm’s liner is 3D printed from a soft, flexible elastomer, which allows it to conform to the shape of your arm. The fluted design also means that it can expand outwards, making it easier to take the arm on and off.


Breathable VentTech™ Liner

The liner also benefits from our VentTech™ design. Breathable vents throughout the liner ensure the heat from your limb can escape, and that fresh air can get in. With the Hero Arm, keeping cool is a breeze.


Washable VentTech™ Liner

It’s important to keep all parts of a prosthesis that are in contact with your skin nice and clean. That’s why we designed the liner to be fully removable, so you can take it out and wash it easily.


Freeze Mode

We know that you want peace of mind when using your prosthesis – that’s why we developed Freeze Mode, so you can temporarily lock the position of the hand and disable the muscle control.
This allows you to freeze the hand with an object held, without worrying about accidentally sending a muscle signal and releasing your grip.
