How do you choose the size of an exoskeleton?
The answer in detail
An exoskeleton's size cannot be deduced from a shoe size or a T-shirt size. Each manufacturer publishes a chart, based on different measurements depending on the device's principle: a support garment is chosen by thigh or waist circumference, a strapped exoskeleton is adjusted in length and circumference.
In our catalog, the Ski-Mojo requires a minimum height of 1.55 m, with a spring chosen according to the user's weight. The Imbrace Gen 2 leggings come in S to 2XL. These are examples: the chart for your model is authoritative.
A chart can also change from one year or version to the next. Before ordering, reread the one on the exact model's product page, and keep a screenshot of the page in case the manufacturer changes it after your purchase.
What varies between models
| Type | Key measurement | Catalog example |
|---|---|---|
| Spring-based ski exoskeleton | height, weight, thigh | Ski-Mojo: 1.55 m minimum, spring by weight |
| Supportive leggings or tights | thigh and waist circumference | Imbrace Gen 2: sizes S to 2XL |
| Passive back exoskeleton | torso size, body shape | Hapo: versions including a women's one (CS) |
| Battery-powered walking exoskeleton | waist, thigh length | chart specific to each brand |
Weights and minimum heights are those on our pages. Always check the manufacturer's official page before ordering.
Step-by-step instructions
- Measure yourself in the morning, without thick clothing: standing height, thigh and waist circumference.
- Note your weight, essential for choosing a spring or an assistance level.
- Compare each measurement with the manufacturer's chart, without rounding up.
- If you fall between two sizes, ask the manufacturer or reseller for advice, in writing.
- On delivery, try and adjust the product before any real use, and send it back quickly if it does not fit.
Common mistakes
Most returns for a wrong size come from a chart misread.
- Choosing from an ordinary clothing size.
- Neglecting weight, which determines the spring of a Ski-Mojo.
- Going below the minimum size stated by the manufacturer.
- Not checking the return conditions before ordering, though they decide what a wrong size costs.
- Measuring over thick clothing, which distorts thigh or waist circumference.
Key takeaways
To choose an exoskeleton's size, measure yourself and compare with the manufacturer's chart: it relies on height, thigh or weight depending on the model. Do not trust a clothing size, respect the stated minimums and check the return policy. Keep the chart and your measurements with the order, they will help in a dispute.
