A few years ago a powered exoskeleton for walking was a lab prototype or a military project. Now you can buy one for less than a good road bike: a motorised belt and thigh cuffs, about the weight of a bag of sugar, that push your legs forward on every uphill step. Hypershell, DNSYS and Ascentiz are the three consumer brands most hikers will meet, all sold online in the UK and all promising that hills will feel easier.
This guide is for walkers curious whether the technology earns its price, and for those with tired legs or long climbs ahead who want an honest comparison. We compared the current models on price, weight, battery range and the makers’ own assistance claims, and set those claims against the published research on wearable exoskeletons.

How we chose
This is a specification and evidence comparison, not a hands-on test: we have not worn these units on the hill. Prices and specifications come from the makers’ own UK and US stores and launch materials, checked in October 2026, alongside hands-on reviews from Wareable, TechRadar, New Atlas and others. Assistance figures such as “39 per cent less exertion” are manufacturer claims and have not, as far as we can find, been tested in peer-reviewed studies. We ranked on how believable the claims are, battery range, weight, water resistance, and the maturity of each company’s support and delivery record.
The hiking exoskeletons, ranked
1. Hypershell X Max S
Hypershell, the best-known consumer brand, reshaped its line-up in 2026 with the S models. The X Max S sits in the middle: one 72Wh battery quoted for 30km in Eco mode, 22Nm of peak torque from two motors at the hip, and a net weight of 1.7kg. Its UK price is £1,299. It is rated IP54 against dust and splashes, which is fine for drizzle but not a downpour on the Cuillin.
The appeal is balance: the range and torque of the flagship Ultra S, in a single-battery package for £400 less. Like every Hypershell, it is marketed as “lifestyle power” and Hypershell is explicit that it is not a medical aid and requires you to be able to walk and balance unassisted.
Price: £1,299
Pros
- Strong range for one battery
- Light for the torque on offer
- Polished app and multiple activity modes
Cons
- IP54 is splash protection only
- Range claims are for Eco mode on Hypershell’s test conditions
2. Hypershell X Pro S
The X Pro S is Hypershell’s entry to the S range: 1.8kg, 18Nm peak torque, one 72Wh battery quoted at 17.5km, and assistance up to 20km/h. It costs £899 in the UK. That is enough for a big day in the Peaks with a spare battery, though not for a long Lakeland round on one charge.
Older Hypershell X models, including the X Go (2kg, 400W peak, up to 15km claimed) and X Carbon (1.8kg, titanium and carbon frame, 17.5km per battery), have been heavily discounted: Hypershell’s Black Friday 2025 pricing had the X Go at £629 and the X Carbon at £1,149, so look for stock deals.
Price: £899
Pros
- Cheapest current-generation model from the market leader
- Same IP54 rating and app as pricier models
Cons
- Range is modest without a spare battery
- Less torque than the Max S and Ultra S
3. Hypershell X Ultra S
The flagship comes with two 72Wh batteries, each quoted for 30km in Eco mode, 22Nm of torque and 1.7kg net weight. Hypershell claims up to 39 per cent less physical exertion and a lower heart rate when climbing; these are company figures. UK price is £1,699.
The second battery is the real difference over the Max S. If you plan to wear it for a full day with big climbs, or on consecutive days without charging, it saves buying a spare.
Price: £1,699
Pros
- Two batteries in the box
- Highest-specification Hypershell
Cons
- Expensive for what is essentially a Max S plus a battery
- Effort-reduction claims are unverified
4. DNSYS Z1
DNSYS’s Z1 is different: it assists at the knee rather than the hip. T3 reported a weight of 680g per leg, twin 450W motors, up to five hours of battery and IP54 resistance, and DNSYS says it offloads up to 150kg of knee pressure. It also claims to recover energy on descents. It launched on Kickstarter in July 2025 at US $699, against an expected US $1,099 retail.
Knee assistance is the most interesting idea here for older walkers and anyone who dreads long descents, but this is a young product and those load figures are the company’s own.
Price: US $1,099 expected retail (Kickstarter backers paid US $699)
Pros
- Targets knees, where many walkers struggle
- Light per leg
Cons
- Unverified load-reduction claims
- Crowdfunded origin, newer support record
5. DNSYS X1
The X1 is DNSYS’s hip unit and the most powerful-sounding of the lot: Wareable measured it at 1.6kg with motors rated up to 1.2 horsepower (about 900W). Pricing in the US runs from US $999 for the Lite to US $1,999 for the Pro, with the X1 Carbon at US $1,299; TechRadar estimated around £950 in the UK in 2024.
Reviews praise the power and adjustability but note complicated setup, short battery life (Wareable got about 70 minutes from one battery in its sport mode on a mountain climb), noise and discomfort under a backpack hip belt.
Price: from US $999 (about £950 in the UK by TechRadar’s 2024 estimate)
Pros
- Very strong uphill assistance
- Highly adjustable fit
Cons
- Short real-world battery life in high-power modes
- Noisy and awkward with a rucksack
6. Ascentiz modular exoskeleton
Ascentiz, linked to Chinese robotics firm RoboCT according to Exoskeleton Report, uses one belt with a 78Wh battery and swappable hip or knee modules. New Atlas reported 1.8kg with the hip module and 2kg with the knee module (excluding battery), 36Nm peak torque, IP54 and a claimed range of up to 50km or ten hours. It raised money on Kickstarter in late 2025 with expected retail of US $1,049 for the hip kit and US $1,149 for the knee kit, and showed at CES 2026.
The modular idea is clever. However, Exoskeleton Report’s user reviews include complaints about late or missing deliveries and slow support, so we would wait for retail stock rather than back a campaign.
Price: hip kit US $1,049, knee kit US $1,149 (expected retail)
Pros
- Hip and knee support in one system
- Large battery
Cons
- Delivery and support complaints
- Heaviest configuration of the group
Do hiking exoskeletons work? What the research says
The science behind powered exoskeletons is solid; the evidence for these particular consumer products is thin.
- Ankle assistance in the real world. Stanford researchers led by Patrick Slade and Steven Collins published a study in Nature in October 2022 on a battery-powered ankle exoskeleton that personalised its assistance outdoors. Compared with normal shoes, it increased walking speed by 9 per cent and cut energy expenditure by 17 per cent, which the NIH summary likened to removing a 20lb backpack.
- Hip assistance. A Harvard team led by Conor Walsh reported in Science in 2019 that a 5kg soft hip exosuit reduced the metabolic cost of walking by 9.3 per cent and running by 4 per cent on a treadmill, as ScienceDaily reported.
Those are lab-grade devices tuned by researchers. Consumer brands cite their own figures, from Hypershell’s 39 per cent exertion reduction to DNSYS’s knee-load claims, and we found no independent peer-reviewed trials of the consumer models. Real benefit probably lies between the two: a noticeable lift on long climbs, little on the flat, and a weight penalty you carry when the battery is flat.
Health note: these are leisure products, not medical devices. If you have a joint condition, a recent injury or balance problems, speak to your GP or a physiotherapist before using one, and do not rely on an exoskeleton to get you off a hill you could not otherwise manage.
Buying guide: what matters with a walking exoskeleton
Hip or knee. Hip units help you lift and swing the leg on climbs; knee units aim to share the load on descents and stairs. Most walkers feel the hip effect more immediately.
Battery in real use. Quoted ranges are in eco modes. In high-power modes, expect a fraction. A second battery is worth more than extra torque.
Weight. At 1.6 to 2kg, every unit becomes dead weight once the battery dies. Plan routes accordingly.
Rucksack fit. Hip-mounted units can clash with a pack’s hip belt. Try one with your usual pack if you can.
Weather. All three brands quote IP54, so treat them as showerproof, not waterproof.
Company track record. Buy from stock with a UK returns route. Crowdfunded products carry delivery and support risk.
What to ignore. Horsepower figures and “feel X kg lighter” claims. Look at range, weight and returns policy.
Hiking exoskeleton FAQs
Are hiking exoskeletons worth it?
For most fit walkers, not yet: a good pair of poles costs a fraction and helps on climbs too. They make more sense for people who want to keep walking big hills despite reduced strength or stamina, or who simply enjoy the technology.
How heavy is a hiking exoskeleton?
Current models weigh about 1.6 to 2kg for hip units. DNSYS’s Z1 knee unit is reported at 680g per leg.
Can an exoskeleton help bad knees?
Knee units such as the DNSYS Z1 and Ascentiz’s knee module claim to reduce load on the joint, but those claims are not independently verified. Ask a GP or physiotherapist before using one with a knee condition.
How far can you hike on one battery?
Makers quote 15 to 30km per battery in eco modes, and Ascentiz up to 50km. In stronger modes, real-world testers have reported as little as an hour or two, so carry a spare.
Are exoskeletons allowed on UK trails?
We know of no UK rule that bars wearing one on a public footpath; it is worn equipment rather than a vehicle. Organised races and challenges set their own rules, so check before you enter.
