For decades, the cultural narrative surrounding the great outdoors has been inextricably linked with the concept of suffering. The romanticised ideal of the alpinist or the long-distance hiker is one of attrition: battling gravity, lactic acid, and the inescapable degradation of the joints. To access the sublime – the high alpine ridges, the secluded valleys – one had to pay a physical toll. This transaction has long defined our relationship with the wild. Yet, a fundamental shift is occurring at the intersection of performance apparel and wearable robotics, challenging the notion that physical deterioration is a mandatory entry fee for the natural world.
Enter the MO/GO (an abbreviation for “Mountain Goat”), a pair of AI-powered hiking pants developed through an unprecedented collaboration between the Canadian high-performance apparel brand Arc’teryx and Skip, a wearable robotics startup that recently spun out of Google’s X labs. Scheduled for commercial release in 2027 with a retail price of $4,999, the MO/GO represents a radical departure from traditional outdoor gear. It is not merely a garment that protects the wearer from the elements; it is an active mechanical partner designed to augment human biomechanics. By integrating a lightweight, battery-powered exoskeleton directly into a pair of hiking trousers, the system promises a 40 percent boost to leg muscles during ascents and critical shock absorption for the knees during descents.
This is the dawn of what the creators are terming “movewear”. It is a concept that sidesteps the clunky, industrial connotations of traditional exoskeletons – often associated with military logistics or clinical rehabilitation – and instead positions robotics as a seamless, consumer-facing lifestyle product. The analogy most frequently deployed by those who have tested the MO/GO is that it functions as an “e-bike for walking”, making the wearer feel roughly thirty pounds lighter. But beyond the immediate physical relief, the project raises fascinating questions about accessibility, the aesthetics of technology, and how contemporary design is increasingly focused on re-engineering the human body rather than taming the landscape.
From the Moonshot Factory to the Mountain
To understand the philosophical underpinnings of the MO/GO, one must look at the origins of Skip. The company was born within the secretive, ambitious confines of X (formerly Google X), Alphabet’s “moonshot factory” tasked with solving seemingly intractable global problems. Skip’s co-founder and CEO, Kathryn Zealand, did not set out to build a luxury hiking accessory. Her initial motivation was deeply personal and grounded in a desire to restore mobility to those who had lost it.
Zealand has frequently cited her grandmother’s experience as the emotional catalyst for the project. After suffering a fall, her grandmother’s world contracted sharply, a common narrative in the ageing population where the loss of mobility directly correlates with a decline in community engagement and overall quality of life. The goal for Skip was to create a technological intervention that could restore that lost autonomy.
Interestingly, the team at Skip arrived at a robotic solution with a degree of reluctance. Speaking to Forbes, Zealand noted: “I actually didn’t want robotics to be the answer. Robots will always be more complicated and expensive than alternate solutions, but years of user research told us that people wanted a product that’s hand-free… and actively helps with the movements that folks found most difficult.”
This user-centric approach led to the realisation that traditional mobility aids – canes, walkers, wheelchairs – often carry a social stigma and fail to assist with the specific, dynamic movements of navigating uneven terrain or ascending stairs. The solution had to be wearable, discreet, and intuitive. It needed to function not as a medical device, but as clothing. The name ‘Skip’, Zealand told Forbes, is a “nod not just to our desire to help people move with ease, but to have that movement unlock all kinds of joyful experiences for them.”
The Arc’teryx Integration: Engineering the Aesthetic of Frictionless Movement
Translating a piece of complex robotics into a wearable garment requires a mastery of textiles and human ergonomics. This is where Arc’teryx, a brand headquartered in North Vancouver with a formidable reputation for over-engineering technical apparel, entered the equation. The Skip team partnered with Arc’teryx’s Advanced Concepts division, a skunkworks team known for pushing the boundaries of material science and construction.
The challenge was immense: how to integrate carbon fibre cuffs, electric motors, and a computer module into a pair of trousers without destroying the garment’s breathability, flexibility, or aesthetic appeal. The foundation chosen for this integration was the Arc’teryx Gamma Pant, a staple in the brand’s lineup renowned for its durable, weather-resistant softshell fabric and articulated patterning.
Designing “movewear” required a paradigm shift for the apparel designers. They were no longer just draping fabric over a static human form; they had to account for the dynamic interplay between the body, the fabric, and a rigid, motorised exoskeleton. The robotic components had to be securely anchored to transmit force effectively without chafing the wearer, while remaining lightweight and entirely detachable. This modularity is a crucial design feature: the hardware can be removed, allowing the Gamma pants to be washed or worn as standard apparel, preventing the garment from becoming a single-use technological novelty.
The psychological impact of this seamless integration has been profound. Cameron Stuart, Manager of Research and Engineering for Advanced Concepts at Arc’teryx, described the testing phase in an interview with TIME magazine. “It’s been emotional seeing early users have a snap realization of, like, ‘Oh my God, this could change my life,'” he remarked. By disguising a mobility aid as premium outdoor gear, the partnership has effectively bypassed the stigma of physical limitation. The wearer does not look like a patient undergoing rehabilitation; they look like a well-equipped alpinist.
The Biomechanics of the ‘Mountain Goat’
The mechanical elegance of the MO/GO lies in its sophisticated use of artificial intelligence and biomechanical engineering. The system is not a passive spring mechanism; it is an active, intelligent partner. Sensors embedded within the hardware continuously monitor the user’s gait, terrain, and intent. This data is fed into a computer module that employs machine learning algorithms to predict the wearer’s next movement in real-time, dictating exactly when and how much torque the motors at the knee joints should apply.
During an ascent, the human body relies heavily on concentric muscle contractions – where the muscle shortens under tension – demanding massive amounts of cardiovascular energy and oxygen. The MO/GO’s motors intervene here, providing a 40 percent power boost that significantly reduces the cardiovascular load.
However, it is during the descent that the technology arguably provides the most critical intervention. Downhill hiking relies on eccentric muscle contractions – where the muscle lengthens under tension to act as a braking system. This is the primary culprit for delayed onset muscle soreness and the acute joint pain commonly referred to as “hiker’s knee”. The MO/GO system shifts its function on the downhill, absorbing the impact forces and supporting the knee joint, effectively acting as an external shock absorber.
Powering this system is a rechargeable battery pack designed to last for approximately three hours of heavy use. Recognising that three hours is rarely sufficient for a serious alpine objective, the design allows for batteries to be swapped out in the field, ensuring the system remains functional on extended expeditions.
The Economics of Augmentation: Democratisation or Elitism?
The advent of consumer-grade exoskeletons inevitably raises questions about access and the economics of the outdoors. At a retail price of $4,999, the MO/GO is prohibitively expensive for the vast majority of consumers. It exists in the uppermost echelon of luxury sporting goods, a price point that seems contradictory to the stated goal of democratising access to the outdoors.
Yet, this tension between high cost and intended accessibility is typical of early-stage, bleeding-edge technology. The transition of exoskeleton technology from the military-industrial complex – where budgets are virtually limitless – to the consumer market requires massive initial capital expenditure. The $99 deposit currently required to reserve a pair for the 2027 production run targets early adopters and affluent outdoor enthusiasts who can subsidise the iterative refinement of the technology.
To mitigate this exclusivity, Skip and Arc’teryx have introduced a rental model. The pants are being made available for hire in select regions, including at hiking clinics near the Stawamus Chief in British Columbia, Canada, for approximately $80 per day. This rental strategy is a shrewd move; it not only generates revenue and real-world testing data but also allows the broader public to experience the technology without the immense financial commitment. It reframes the MO/GO from a luxury purchase into a widely accessible service, aligning more closely with Skip’s original mission of restoring joy and mobility to the masses.

The Future of the Augmented Body
The introduction of the MO/GO pant by Arc’teryx and Skip is a watershed moment in contemporary design and wearable technology. For centuries, our approach to the outdoors has been defined by modifying the environment to suit our vulnerabilities – building smoother trails, constructing funicular railways, and erecting heated alpine huts. The MO/GO represents an inverse philosophy: we are now choosing to augment the human body to meet the harsh, uncompromising demands of the landscape.
This shift from environmental modification to human augmentation carries profound cultural implications. If a motorised pant can effectively erase thirty pounds of perceived weight and eliminate the joint pain associated with ageing, it redefines what we consider a “natural” physical limitation. The boundaries of exploration are no longer dictated entirely by one’s chronological age or genetic biomechanics, but by one’s access to augmenting technology.
As we look toward the 2027 release date, the MO/GO stands as a fascinating case study in the evolving definition of apparel. Clothing is no longer merely a passive barrier against the cold or the rain. In the hands of Skip and Arc’teryx, it has become an active, intelligent extension of the human musculoskeletal system. The “e-bike for walking” has arrived, and it promises to reshape not just how we move through the mountains, but who gets to experience them.
