Ski-Mojo or Stoko K1 for skiing: which one to choose?

Q: Ski-Mojo or Stoko K1 for skiing: which one to choose?

The Ski-Mojo (699 euros) is a mechanical spring exoskeleton that takes over part of the load on the thighs, with no battery. The Stoko K1 (388 dollars) is a cable support tights of about 450 g, worn under trousers. The first assists more, the second is more discreet and cheaper.

The answer in detail

These two products meet the same wish, skiing longer without suffering knees or thighs, but through different principles. The Ski-Mojo is an external device: a thigh harness connected by an articulated rod to a fixing on the boot, with a spring chosen by weight.

The Stoko K1 is a garment: tights integrating a network of cables, adjusted by dials, to support the knee without a rigid structure. Our page presents it as a class 1 medical device (FDA and Health Canada), which remains a manufacturer statement. One adds a device to the body, the other goes on like a garment: the difference is felt mostly when getting dressed, on lifts and at the end of the day.

Limits and precautions

Stated effects come from manufacturers, with no independent measurement read.
Neither is a treatment: for persistent pain, consult a health professional.
The Ski-Mojo requires setting the spring according to weight.
This is not medical advice: ask a doctor's opinion with a knee condition.
