Hypershell · Size & fit
Measure your body.
Align the device.
Then test the fit.
Waist, hip width and thigh length tell you more than height alone. Start with the measurements before choosing a model.
A correct Hypershell fit depends on body proportions and hip-joint alignment—not height alone. Before ordering, record your height, weight, waist circumference, hip width and thigh length. Hip width is a straight measurement across the body, not a tape wrapped around your hips; thigh length is not your trouser inseam.
This guide explains those measurements and the first-fitting sequence for Hypershell X Series S. The numerical ranges and wearing steps below come from the S-series User Manual v1.3, dated July 2026. Original X-series owners should use their corresponding manual; these are not Halo fitting instructions.
Measurements are an initial screen. They do not prove comfortable alignment, safe use or medical suitability. Hypershell’s online fit checker also describes its result as a preliminary reference.
Start with the supported S-series size range
The following manual ranges apply to Hypershell X Pro S, X Max S and X Ultra S. Selecting a different power level or battery kit does not replace these body-size checks.
| Measurement | Manual range | What to check |
|---|---|---|
| BMI | 16–32 | Calculated from height and weight; not a substitute for the three dimensional measurements. |
| Waist circumference | 72–122 cm / 28.3–48 in | Wrap the tape through the navel and the tops of the pelvic bones. |
| Hip width | 31–42 cm / 12.2–16.5 in | Straight, horizontal distance between the outer hip landmarks—not hip circumference. |
| Thigh length | 36–50 cm / 14.1–19.6 in | Straight distance from the outer hip landmark to the outer knee landmark—not inseam. |
On a phone, swipe inside the table. Keyboard users can focus the table area and use the arrow keys. Inch values are the manufacturer’s published approximations. Source: body-size tables, printed pages 46–47.
The manual also provides height-and-weight reference tables. Those tables are based on limited samples; they are not a universal promise that everyone within a headline height range will fit.
How to take the five measurements
Use a flexible measuring tape and record centimetres consistently. A helper can make the two straight-distance measurements easier. Repeat an uncertain reading before entering it in the fit checker; a small recording mistake can change the recommended adjustment.
1. Height and weight: a starting point
Record your current height and weight rather than an old estimate. BMI is weight in kilograms divided by height in metres squared. This helps interpret the manual’s reference, but two people with the same BMI can have different hip widths and thigh lengths.
Do not stop after entering height and weight. A model can be powerful enough for your intended activity and still be unsuitable for your body geometry.
2. Waist circumference: do not use your jeans size
Hypershell’s measurement instructions place the tape around the body through the centre of the navel and the tops of the pelvic bones. Breathe normally. Keep the tape close to your body without pressing it into the skin.
A trouser label is not a reliable substitute. Clothing brands can measure at different positions, and a nominal 32-inch waist is not necessarily your measured circumference at these landmarks. Measure the body directly; do not pull the tape tighter to reach a preferred number.
3. Hip width: a straight line, not a loop
Locate the bony prominence on the outside of each hip—the greater trochanter. Measure the horizontal, straight distance between those two landmarks, keeping the measurement parallel to the ground. The manufacturer’s illustration distinguishes this from wrapping the tape around the body.
This number matters because the S manual uses hip width to recommend the hip lever tube adjustment value in Hypershell+. It helps position the motors beside your hip joints. A circumference entered as width can produce an unsuitable recommendation.
If you cannot identify the landmarks confidently, seek help rather than substituting a clothing measurement or estimating from a photograph.
4. Thigh length: do not enter your inseam
With the body standing straight, measure the straight distance from the greater trochanter at the outside of the hip to the lateral epicondyle at the outside of the knee. Follow the official diagram’s endpoints. Do not follow the curve of the leg or measure from the crotch.
Waist, hip width and thigh length answer separate questions. A waist measurement within range does not make an out-of-range thigh measurement acceptable, and a larger model name is not a larger clothing size.
Fit the S-series hip belt with the device off
Prepare the body measurements in Hypershell+ and follow the corresponding manual’s onboarding instructions. Complete mechanical adjustments and put the device on correctly before powering it on. Do not move the adjustment mechanisms while the device is actively assisting you.
- Set the hip lever tubes. Use the app’s recommended value based on hip width and set the left and right sides to the same value, as the manual instructs. Confirm the adjustment is secured.
- Position the rear support. Centre it against the spine/sacrum area and place the hip belt on the iliac crest—the upper pelvic bone area—rather than letting it hang like a loose trouser belt.
- Position and fasten the front buckle. The manual’s baseline is about 1 cm below the navel. It gives a lower, roughly 2–3 cm position for the BMI 24–32 group; that is a specific fitting instruction, not a reason for every wearer to lower the belt.
- Check motor alignment. The motors should line up with the hip joints, with approximately 0.5–1 cm between the motors and the body in the manual’s fitting guidance.
- Check security and comfort. The belt should hold position without painful pressure. If the hardware cannot align comfortably, stop and reassess the measurements instead of tightening harder.
The motor gap is not a knee-clearance measurement. Do not apply one distance to every part of the device. Nor should you enlarge a gap arbitrarily to work around discomfort: alignment must remain correct.
Fit the leg belts above the knee, not in the knee fold
Adjust the leg levers to follow the knee centre as shown in the S manual. Keep the leg belt sliders at least two finger widths—approximately 3 cm—above the knee. The rear straps should run horizontally across the back of the thigh, not through the crease behind the knee.
The 3 cm instruction concerns the sliders’ position. It does not mean leaving a loose 3 cm gap between a strap and your leg. Keep straps secure and comfortable, without pinching or restricting normal movement.
For walking, the manual describes moderately snug leg belts; running and cycling call for tighter fastening. That never means accepting pain, numbness or circulation restriction. If the belt slides, correct its placement and fastening with power off rather than allowing it to migrate toward the knee.
Recheck the fit when clothing changes
Wear the device over clothing, not against bare skin. Avoid loose or dangling fabric that can interfere with moving parts. For Canadian use, changing from thin trousers to winter layers is a reason to repeat the fit check—not evidence that all winter outfits will work.
Measure your body using the official method first. Then assess the belt and lever positions over the clothing you intend to wear. Do not substitute a thick jacket’s circumference for the body measurement or assume that a summer adjustment remains appropriate.
Standing wear detection: what four orange lights mean
After the device is correctly worn, follow the manual’s power-on and app-binding sequence. The S series checks wearing automatically when powered on. Stand correctly for this check; the manual notes that a seated position can cause detection to fail.
All four LEDs blinking orange indicate a wearing-detection failure. That pattern is not the same as a low-battery indication. Check the wearing position, buckles and straps. If mechanical adjustments are needed, switch off first; once properly worn and standing, the manual instructs pressing the control button once to repeat detection.
Do not repeatedly retry to force acceptance of poor fit. If orange failures happen during use despite securely fastened belts, the manual directs you to record a video and contact Hypershell technical support. All four LEDs blinking red indicate a device error, not merely a sizing issue; follow the app message and support instructions.
A controlled first-fit checklist
The Safety Guidelines advise a safe indoor setting for first use. Save the trail, stairs and uneven terrain for later; a first fitting should not require you to recover your balance around hazards.
- Before wearing: confirm the applicable manual, body measurements, eligibility requirements and clothing. Check the hardware with power off.
- At the hips: check equal tube settings, rear centring, belt position, buckle position and motor alignment.
- At the legs: check lever direction, slider clearance and rear strap position. Confirm that nothing sits in the knee fold.
- Before assistance: cautiously check comfortable, normal movement with the device off in a clear indoor area. Stop if anything pinches or shifts; this practical check is not a certification of fit.
- After power-on: complete standing wear detection and the manual’s onboarding. Proceed only with correct fit and normal operation; stop for pain, instability or error indications.
- When removing: switch off first and support the rear lever while releasing the hip belt, as instructed, so the device does not drop.
Body measurements do not establish eligibility. Hypershell is not a medical or rehabilitation device and does not provide balance assistance, fall prevention or pain treatment. Read the Safety Guidelines’ user restrictions and medical-clearance requirements before use, especially where a condition affects walking, coordination or balance.
What to ask before ordering in Canada
Ask for help before ordering if a measurement is outside the manual’s range, readings differ substantially, landmarks are unclear, or comfortable joint alignment seems doubtful. Send the five measurements, the exact model, and a short description of the intended activity and clothing.
Ask what fitting assistance is actually available. Do not assume a local demonstration or try-on is included. A size-check result is not a fit guarantee or a statement of return eligibility; confirm applicable purchase terms separately.
For the original Hypershell X series, select the corresponding original manual from the official tutorials and manuals page. Do not silently reuse the S-series table or control sequence for another generation.
Once fit is understood, use our X Series vs X Series S guide for generation differences, or the X Pro S vs X Max S vs X Ultra S guide for model and kit selection. Those are buying comparisons; this page is the measurement and wearing reference.
Hypershell sizing FAQs
Is height alone enough to choose a Hypershell?
No. Record height, weight, waist circumference, hip width and thigh length. Body proportions affect alignment, and the online fit checker is only a preliminary reference.
Is hip width the same as hip circumference?
No. Hip circumference wraps around the body. Hypershell hip width is the straight, horizontal distance between the outer hip landmarks. Entering one in place of the other can give an unsuitable adjustment recommendation.
Can I use the waist size on my jeans?
Measure directly instead. Hypershell specifies a tape position through the navel and tops of the pelvic bones; a trouser label may describe a different position or nominal size.
Can I use my trouser inseam for thigh length?
No. The official thigh measurement runs from the outer hip landmark to the outer knee landmark. It is not measured from the crotch and does not follow the curved surface of the leg.
Does X Ultra S fit a larger body than X Pro S?
The S manual gives the same body-size reference for X Pro S, X Max S and X Ultra S. A higher model designation is not permission to exceed the published size range.
Should the hip motors press directly against my body?
The S manual calls for hip-joint alignment and an approximate 0.5–1 cm motor-to-body gap during fitting. This is separate from the leg-slider clearance above the knee. Stop if hardware presses painfully.
What if all four lights blink orange?
That indicates failed wearing detection. Check fit and stand correctly; make adjustments with power off. Once correctly worn, press the control button once to retry as instructed. Persistent failures during use with secure belts require manufacturer support.
What if my measurements are outside the S manual’s range?
Ask manufacturer technical support about the exact model and whether a physical fitting assessment is appropriate. Do not assume that another model, a larger adjustment or the general size webpage guarantees compatibility.
Can I start by testing it on a hiking trail?
Use a safe indoor setting for first use, following the Safety Guidelines and your model’s manual. A trail is not an appropriate place to discover a loose belt, poor alignment or a detection problem.
