Ski-Mojo: The #1 Ski Exoskeleton

The Ski-Mojo comes in three distinct models — Blue, Silver and Gold — and the choice is made exclusively on your body weight, without ski equipment. Neither your height, nor your level of practice, nor the length of your legs comes into this decision: it is only your weight that determines the spring tension you need to get optimal assistance.

Why is weight the only criterion? The Ski-Mojo works through a mechanical spring system that has to offset about one third of your body weight on each flexion. If the spring is too light for your weight, it will not be strong enough to relieve you effectively. Conversely, a spring too strong for your build will be hard to compress and will make skiing uncomfortable, even tiring. Precise calibration by weight is therefore the key to optimal operation.

No, the Ski-Mojo is designed to be worn completely invisibly under your ski pants in the vast majority of cases. It is one of the device's most appreciated features, and an important criterion for skiers who care about their appearance on the slopes or simply do not want to attract attention.

Why does the Ski-Mojo go unnoticed? The Ski-Mojo consists of two exoskeleton legs connected by a discreet harness around the waist. The legs run along the outside of your thighs and shins, following the natural shape of your lower limbs. Their slim profile — only 9 cm wide — lets them slip easily under most commercial ski pants, whether fitted or slightly flared.

The black neoprene sleeve covering the Ski-Mojo's mechanical parts also contributes to its discretion: it gives the whole a smooth, uniform look, with no roughness or protruding parts that would create visible relief under the fabric.

What type of pants suits best? The Ski-Mojo is compatible with the vast majority of ski pants on the market. It goes under a standard straight or slightly flared ski pant without difficulty. On the other hand, ultra-slim ski pants or ones very fitted at the knees and shins can be trickier: in that case the Ski-Mojo remains functional but may create slight relief marks visible on the stretched fabric.

If you are buying ski pants specifically to use with your Ski-Mojo, opt for a slightly roomier cut than usual at the legs, or choose a model with a soft lining that adapts easily to shapes. Waterproof-membrane pants (Gore-Tex type) are generally more supple and accommodating than rigid-shell pants.

And under snowboard pants? Snowboard pants, generally roomier and longer than alpine ski pants, are particularly well suited to wearing the Ski-Mojo. The baggy or regular cut of most models leaves plenty of room for the two exoskeleton legs, with no constraint and no visibility of the device.

Is the harness visible under the jacket? The Ski-Mojo harness is worn around the waist, over your thermal underwear or mid-layer, and under your ski jacket. It is thin, flat and does not create a visible bump under a standard ski jacket. Only the top edge of the harness may slightly show if you wear a very short jacket that does not fully cover your waist — a very rare case with current ski jackets, generally designed to cover the belt line.

Can it be worn over the pants? Technically yes, the Ski-Mojo can also be worn over the pants, especially for the first uses to make adjustments and getting used to it easier. Some users in fact prefer this configuration for easier access to the disengagement mechanism. In this case the device is naturally visible, but it poses no technical problem. On the slopes you will meet more and more skiers wearing their Ski-Mojo openly, who often become genuine ambassadors for the product with curious people who ask them about it.

A telling anecdote. Many users report regularly meeting other skiers on the slopes who ask them “what they are wearing under their pants” — not because the Ski-Mojo is visible, but because they visibly ski better and for longer than the others, sparking the curiosity of those around them. The Ski-Mojo's discretion is therefore real: it is not the equipment you notice, it is the performance it generates.

The Ski-Mojo comes with a 24-month manufacturer's warranty from the purchase date, extendable to 48 months after online registration on the manufacturer's official website. It is one of the most generous warranties in the sports exoskeleton market, and a strong signal of the confidence the manufacturer has in its product's durability.

The standard 24-month warranty. From the moment you buy your Ski-Mojo, you automatically get a two-year warranty covering manufacturing defects and malfunctions linked to materials. This warranty is valid without any particular step: you just need to keep your proof of purchase. It covers all components of the kit delivered in the box — the two exoskeleton legs, the harness, the connectors and the mechanical parts — against any original defect.

In practice, if a spring proves defective, if a fastening part has a manufacturing problem or if the neoprene sleeve comes apart abnormally under normal conditions of use, the manufacturer covers the repair or replacement of the part concerned at no cost to the user.

The extension to 48 months: how to get it? To take your warranty from 24 to 48 months, you just need to register your product online on the official Ski-Mojo site in the weeks following your purchase. This step is simple, free and takes less than five minutes. It involves entering your contact details, your model (Blue, Silver or Gold) and your proof of purchase. Once the registration is validated, your warranty is automatically extended to four years.

This registration has a double advantage: it extends your coverage and also lets the manufacturer contact you directly in case of a technical update or product recall, which is an additional guarantee of safety and quality follow-up.

What exactly does the warranty cover? The Ski-Mojo warranty covers defects in material and workmanship under normal conditions of use. In particular, it includes:

• Structural defects on the exoskeleton legs
• Malfunctions of the spring system not related to normal wear
• Original fixing or assembly problems
• Defects on the harness and connectors supplied in the original pack

What the warranty does not cover. Like any manufacturer's warranty, the Ski-Mojo's excludes certain cases. Generally not covered are:

• Normal wear of parts from intensive use over several seasons (notably the neoprene sleeves and the boot connectors)
• Damage caused by a violent fall or a significant mechanical shock
• Damage resulting from poor installation or incorrect adjustment made without following the manufacturer's instructions
• Use of the Ski-Mojo in conditions not intended by the manufacturer (sports other than skiing and snowboarding)

For these cases, spare parts are available for separate purchase in the official shop, which lets you extend the Ski-Mojo's life well beyond the warranty period.

The Ski-Mojo's durability in practice. Beyond the warranty, it is worth noting that the Ski-Mojo is known for its exceptional longevity. Made in France with high-quality materials, it is designed to withstand many seasons of intensive use. Many users say they have had their Ski-Mojo for five, six or seven years without needing to replace anything other than the boot connectors — inexpensive wear parts available as an accessory.

The manufacturer also offers a servicing and maintenance service for older models, to check the condition of the springs, replace wear parts and make sure the device still works optimally. This service is particularly recommended every two to three years for regular users.

A long-term investment. With a warranty of up to 4 years and an actual lifespan often above 7-10 years depending on maintenance, the Ski-Mojo clearly fits a logic of durable investment. Measured against the number of ski days gained and pain avoided, its cost per use becomes very reasonable over several seasons.

Does the Ski-Mojo work for snowboarding?

Yes, the Ski-Mojo is fully compatible with snowboarding. While the product is historically known and sold under the name “Ski-Mojo”, its use is not limited to alpine skiing: it was designed and tested to work with both snow-sliding disciplines, and many snowboarders use it with satisfaction season after season.

How does the Ski-Mojo work in snowboarding? The Ski-Mojo's mechanical principle stays the same in snowboarding: the springs absorb part of the pressure on the legs during flexion phases, relieve the knees and thighs, and return the energy on extension. In snowboarding, these compression phases are just as present as in alpine skiing — notably in frontside and backside edge turns, jump landings or long traverses in a bent position.

Snowboarding loads the legs slightly differently from skiing: the body faces sideways, both feet are fixed to the same board and weight distribution varies constantly between the front and rear leg. The Ski-Mojo adapts perfectly to this specific body mechanics, assisting each leg independently thanks to its two separate spring units (one per leg).

Snowboard connectors: an essential adaptation. The main difference between ski and snowboard use lies in how the Ski-Mojo attaches to the boots. In alpine skiing, the device connects to the rigid ski boots via specific connectors glued to the shell. Snowboard boots, whether soft or hard, have a different shape and materials that require dedicated snowboard connectors.

These snowboard connectors are available as a separate accessory in the official shop. They are designed to fit the most common snowboard boots on the market and guarantee a reliable, secure attachment for the whole session. If you snowboard exclusively, remember to order them together with your Ski-Mojo so you can use it as soon as the package arrives. If you do both disciplines, you will simply need both types of connectors — the ski connectors being included in the base pack and the snowboard connectors being ordered separately.

Specific benefits for snowboarders. Snowboarders get the same advantages as skiers, with a few benefits particularly appreciated in their discipline:

Knee protection is one of the strengths most often cited by snowboarders using the Ski-Mojo. The front knee (the one facing downhill) is particularly stressed in snowboarding, notably in toeside turns that demand deep, prolonged flexion. The Ski-Mojo significantly reduces the stress on this knee, which is a real boon for riders with chronic pain or ligament after-effects.

Reduced end-of-day fatigue is also much appreciated in snowboarding, a discipline where sessions can be long and intense, notably in the snowpark or freeride where efforts are repeated and explosive. With the Ski-Mojo, snowboarders report being able to keep a higher intensity at the end of a session, where muscle fatigue would normally have hampered their riding.

Shock and vibration absorption is another benefit particularly relevant in snowboarding, a discipline where trick landings, crossings on hard snow or runs on bumpy slopes generate significant impacts on the joints. The Ski-Mojo's springs cushion part of these impacts, preserving the knees and hips over time.

Are there snowboarding situations where the Ski-Mojo is less suitable? As in alpine skiing, the Ski-Mojo has some limitations in very specific situations. In snowboarding, the system can be slightly restrictive when walking on the flat with the board on your feet — notably to get around the resort or go up a flat section. The disengagement mechanism, however, lets you deactivate the springs in a few seconds for these passages, before reactivating them for the ascent.

Snowboarders who exclusively ride the freestyle snowpark, with tricks involving large rotations and very asymmetrical positions, will also need a few sessions to get used to the device before using it at maximum intensity.

The Ski-Mojo, a longevity tool for all riders. Whether alpine skiing or snowboarding, the Ski-Mojo answers the same reality: snow sliding is physically demanding, and the joints deserve to be protected so the passion lasts as long as possible. Many snowboarders who have adopted the Ski-Mojo say they have made it part of their permanent equipment, alongside their helmet or wrist guards — not as an admission of weakness, but as a smart choice to preserve their joint capital and keep riding season after season.

Is the Ski-Mojo suitable after knee surgery?

This is one of the most important and most frequently asked questions from skiers considering buying a Ski-Mojo. The answer is nuanced but broadly very encouraging: yes, the Ski-Mojo is suitable for skiing after knee surgery, subject to prior medical advice and a gradual return to activity. It is in fact one of the most represented user profiles in the Ski-Mojo community, and there are many eloquent accounts of people who got back on the slopes thanks to this device after surgery.

Why the Ski-Mojo is particularly relevant post-operatively. Knee surgery — whether an anterior cruciate ligament (ACL) reconstruction, a meniscectomy, a chondroplasty or a partial or total knee replacement — leaves the joint in a state of temporary or permanent fragility. Even after full rehabilitation and a medical green light to resume sport, the operated knee often remains more sensitive to mechanical stress than the healthy opposite knee.

Alpine skiing is precisely one of the most demanding sports for the knees. Every turn generates compression, shear and torsion forces on the joint. For an operated knee, this stress can cause pain, inflammation or apprehension that spoil the enjoyment and slow the return. That is exactly where the Ski-Mojo comes in: by absorbing about one third of the pressure on each knee, it mechanically reduces joint stress and lets the operated knee work under much more favorable conditions.

Which operations benefit most from the Ski-Mojo? All knee surgeries can potentially benefit from the Ski-Mojo's assistance, but some conditions gain particularly markedly:

ACL reconstruction is the most common ligament injury in skiing. ACL reconstruction requires long rehabilitation (6 to 12 months), and returning to skiing can generate significant apprehension, even after successful rehab. The Ski-Mojo reduces mechanical stress on the knee in turns and offers extra security that helps you regain confidence gradually.

Meniscectomy (partial or total removal of a meniscus) is a very common procedure that often leaves the knee more vulnerable to axial compression. Without a meniscus or with a reduced one, the knee cartilage takes more of the shocks. By absorbing part of the load, the Ski-Mojo acts as a sort of external artificial meniscus, protecting the remaining cartilage in the long term.

Knee replacement (total or unicompartmental) concerns more and more active senior skiers. After a successful replacement and full rehabilitation, many surgeons allow a return to skiing on groomed slopes. The Ski-Mojo lets you approach this return with much more peace of mind, limiting the stress on the prosthesis and reducing the muscle fatigue that could compromise joint stability.

Double ligament reconstruction (notably ACL and medial collateral ligament) is a serious injury with a long convalescence and a sometimes uncertain return to skiing. Several Ski-Mojo users say they were able to ski again several years after their injury thanks to this device, when they had abandoned all hope of putting skis back on.

The absolute precaution: prior medical advice. While the Ski-Mojo has remarkable potential for post-operative skiers, it must be stressed that its use must be validated by your doctor or orthopedic surgeon before any return to skiing. The Ski-Mojo is not a medical device — it does not treat, does not rehabilitate and does not replace appropriate medical follow-up. It is a mechanical assistance tool that can make sporting practice easier, but only for a sufficiently consolidated knee and a completed rehabilitation.

Your surgeon is the only one able to assess whether your knee is ready for skiing, with or without assistance. In some cases — a knee still inflamed, a ligament still consolidating, a recent prosthesis — skiing may be contraindicated regardless of the Ski-Mojo. Only once the medical green light is obtained can the Ski-Mojo come into play as a facilitator of the return.

It is also advisable to talk to your physiotherapist: as a rehabilitation professional, they can guide you on how to integrate the Ski-Mojo into your gradual return, adapting the goals of each session to your real level of recovery.

How to approach returning to skiing with the Ski-Mojo after surgery? Returning to skiing post-operatively with the Ski-Mojo should follow a reasoned progression. Here are some practical recommendations from users who have been through this:

Start with green and blue runs with little elevation, avoiding tight turns and bumpy areas in the first sessions. The goal is to rediscover the sensations of skiing and test your knee in controlled conditions before gradually increasing the difficulty.

Limit the duration of the first outings to two or three hours at most, even if you feel fine. The operated knee can send pain or inflammation signals with a delay — so-called “delayed pain” — and a session that is too long on return can cause an inflammatory reaction the next day.

Listen to your body and do not try to compensate for the protection offered by the Ski-Mojo by taking extra risks. The Ski-Mojo reduces mechanical stress but does not make the knee invulnerable. Respect your physiological limits, especially in the first weeks back.

Finally, remember to ice your knee at the end of the day, even in the absence of pain, during the first weeks back. It is a simple precaution that prevents inflammation and promotes optimal recovery between sessions.

Testimonials that speak for themselves. Among the Ski-Mojo's 88 verified reviews, several accounts perfectly illustrate the device's value post-operatively. One user says she got back on the slopes after seven years away following a double ligament reconstruction — anterior cruciate and medial ligament. Another, aged 70 with severe osteoarthritis in both knees and no remaining cartilage, now strings together descents all day without joint pain. A third user, suffering from a meniscal tear, says he felt no pain on the slopes thanks to the Ski-Mojo, when he could no longer ski without it.

These accounts are not medical promises, but they illustrate the remarkable potential of this device for users who thought they had closed the book on skiing for good.

The Ski-Mojo, a companion for sporting longevity. Beyond the post-operative question, the Ski-Mojo fits a broader philosophy: letting everyone ski for as long as possible, preserving their joint capital and adapting the intensity of effort to the real abilities of their body. Whether you are returning after surgery, preventing progressive joint wear or simply want to ski longer without pain, the Ski-Mojo is an investment in your sporting longevity.
