Hypershell X Pro S vs Max S vs Ultra S: How to Choose

The Hypershell lineup here comes in three versions: the X Pro S, the X Max S, and the X Ultra S. You can browse all three on the exoskeletons collection page, but the real question is which one to buy.

Same Harness, Same Size Range

All three models use the same hip harness and cover the same size range. If a certain fit works for you on one model, it works the same way on the other two — fit is answered once, regardless of which model you pick. To check where you fall in that range, see the fit guide.

With fit settled, the choice comes down to three things: how much power and range you want, how many batteries you want on hand, and how much you value lighter, stronger materials plus two extra terrain modes.

Hypershell X Pro S: Built for Half-Day Outings

The Hypershell X Pro S is priced at $1,199. It runs two motors at 18 N·m each, for a maximum output of 800 W. Its 72 Wh (5,000 mAh) battery is removable and charges at up to 65 W, reaching 50 percent in about 35 minutes. On the Eco 30 setting, one battery covers 10.9 mi (17.5 km). Maximum assisted speed is 12.4 mph (20 km/h), across 10 adaptive assist modes. Wearing weight, battery included, is 5.7 lb (2,585 g).

Its hip lever is stainless steel, the main tube is aluminium alloy, and the leg lever is carbon-fibre reinforced polymer. Like the other two models, it carries an IP54 weather rating.

This is the model to consider if your outings run half a day: a morning hike, a few hours on varied ground, a day of errands on your feet. Its range and top speed are the lowest of the three, but for a shorter outing that ceiling is unlikely to matter.

Hypershell X Max S: Built for Longer Days

The Hypershell X Max S is priced at $1,799. It shares the Pro S's battery format, charging speed, materials, weather rating, and 10 assist modes, but steps up the motors to 22 N·m each, for a maximum output of 1000 W. Range on Eco 30 rises to 18.6 mi (30 km) per battery, and maximum assisted speed rises to 15.5 mph (25 km/h). Wearing weight, battery included, is 5.7 lb (2,571 g).

The move from the Pro S to the Max S is a move in power and range, not in materials. The hip lever, tube, and leg lever are the same stainless steel, aluminium alloy, and carbon-fibre reinforced polymer as the Pro S. If your days run longer, or you want more torque and speed in reserve, this is the step that gets you there without changing the fit or the build.

Hypershell X Ultra S: Built for Extended Trips and Demanding Terrain

The Hypershell X Ultra S is priced at $2,399. Output and torque match the Max S exactly: 1000 W maximum, 22 N·m per motor across two motors. Maximum assisted speed is also 15.5 mph (25 km/h), and range on Eco 30 is 18.6 mi (30 km) per battery. The difference is that the Ultra S includes two 72 Wh anti-cold batteries rather than one. With a charged spare on hand, you can swap batteries in the field and continue for another 18.6 mi (30 km) without stopping to recharge.

The Ultra S also moves to a different set of materials: a titanium alloy hip lever, a titanium alloy tube, and a carbon-fibre leg lever. Wearing weight, with one battery installed, is 5.6 lb (2,538 g) — lighter than either the Pro S or the Max S, even though a second battery ships with the unit. It also adds two assist modes beyond the 10 shared by the Pro S and Max S, for 12 in total, with the two additional modes built for dune and snow conditions.

The step from the Max S to the Ultra S is not a step in power, since output and torque are identical to the Max S. It is a step in what the unit is made from, how many batteries ship with it, and how many terrain-specific modes it offers. That combination lines up with trips that run longer than a day, or that cross terrain like sand or snow where the extra modes apply.

The Two Real Upgrade Steps

Looked at together, the three models represent two distinct upgrade steps, not three unrelated products.

The first step, from the X Pro S to the X Max S, is a step up in output. Torque per motor rises from 18 N·m to 22 N·m, maximum output power rises from 800 W to 1000 W, range on Eco 30 rises from 10.9 mi (17.5 km) to 18.6 mi (30 km), and maximum assisted speed rises from 12.4 mph (20 km/h) to 15.5 mph (25 km/h). Materials, battery format, charging, and the number of assist modes stay the same.

The second step, from the X Max S to the X Ultra S, does not touch output power or torque at all — both stay at 1000 W and 22 N·m per motor. What changes is the build: titanium alloy in place of stainless steel and aluminium alloy, carbon fibre in place of carbon-fibre reinforced polymer, a second battery included in the box, and two additional assist modes for dune and snow conditions.

Which One Should You Buy?

  • Half-day outings: the Hypershell X Pro S matches the shortest range and lowest top speed of the three to the lowest price.
  • Longer days: the Hypershell X Max S adds power, range, and top speed over the Pro S, while keeping the same materials and single-battery setup.
  • Extended trips and demanding terrain: the Hypershell X Ultra S adds a second battery, lighter and stronger materials, and two modes built for sand and snow.

If you are weighing the numbers side by side, the comparison page lays out all three models in one place.

Checking Fit and Getting Help

Since the harness and size range are identical across all three models, you only need to confirm your fit once. Start with the fit guide. For anything else, contact us directly.

If you order and change your mind, you can return the unit within 30 days of delivery, provided it is unused, with tags attached, and in its original packaging.
