The suit has two parts, a backpack that provides power and processing, and two strap-on exoskeleton parts for the legs, intended to offer support to your knees and quads. You can use it for both skiing and snowboarding, Roam says, though this is still a prototype – the final design might look different to the pictures you see here.

Through a combination of sensors and software calculations, the exoskeleton adjusts torque at the knee to support what your legs are already doing, and the accompanying app for Android and iOS lets you adjust just how much help the exoskeleton offers. Roam says it's like having "intelligent shock absorbers" on your legs.

Roam suggests the device could help advanced skiers push through harder turns and recover from injury more quickly, while helping casual and elderly skiers stay out on the slopes for longer – the exoskeleton takes on some of the strain on the legs, meaning the usual limb fatigue or pain associated with a day's skiing takes longer to set in.
