This listing is for the EMS underwear set only — one short-sleeve top and one pair of knee-length shorts. The training vest, electrode pads, powerbox and machine are sold separately.
EMS Underwear for Xbody Machines – Lyocell Base Layer Set
This lyocell EMS underwear is the thin base layer worn directly against the skin under the training vest. The stretchy, close-fitting set keeps the vest's electrode pads in full, even contact with the body during a muscle stimulation session, so pulses distribute smoothly across every contact zone.
The fabric is built around 47% lyocell for one reason: lyocell absorbs and holds water. Before a session you dampen the garment with clean tap water (or your studio's conductive spray), and the moist fabric becomes the conductive layer between skin and electrodes — that is how the stimulation reaches the muscles. Ordinary cotton sportswear dries out within minutes and causes weak spots or hot spots; a damp lyocell base layer stays even through a full 20-minute session.
Compatible with Xbody Newave, Xbody DryTech, and other wired and wireless EMS training systems that use a vest-over-base-layer setup. Not affiliated with or endorsed by Xbody — third-party compatible apparel.
Key Features
- 47% lyocell blend — 47% lyocell + 44% polyamide + 9% elastane; the lyocell holds moisture so the garment stays evenly conductive session after session
- Two-piece set — one short-sleeve top and one pair of knee-length shorts, covering the torso and thigh zones under the vest
- Second-skin fit — four-way stretch keeps the vest and pads flush against the body, shifting less during squats, lunges and floor work
- Made for studio use — fabric and seams withstand frequent machine washing between clients without losing shape
- Quick turnaround — machine washable and fast air-drying for back-to-back sessions
- Five sizes — S through XXL, covering heights from about 155 cm to 185 cm
Who Is It For
- EMS fitness studios and personal trainers running wired or wireless vest systems
- Fitness and wellness centers offering electro-muscle-stimulation sessions
- Gyms and sport performance studios
- Home users needing replacement or spare base layers
- Distributors stocking studio consumables in bulk
How to Wear and Care
- Put the set on before fastening the vest and electrode pads.
- Spray or dab clean tap water over the electrode contact zones until the fabric is damp — not soaking. A stinging or pinching feeling during a session means a spot has dried out; dampen it again.
- Fasten the vest over the underwear and start the session as usual.
- After use, machine or hand wash in cold water with mild detergent, rinse well and air dry in the shade. Do not tumble dry, iron or bleach.

Wholesale & Custom Orders
EMS underwear is a studio consumable — sets are washed between clients and replaced regularly, so most studios reorder every few months. We offer bulk pricing for studios, gyms and distributors, plus custom logo printing on the garment for bulk orders (customers provide artwork they hold the rights to use). Contact us for quantity pricing and lead time.






Frequently Asked Questions
Is this underwear compatible with Xbody Newave and DryTech?
Yes. This is a third-party compatible base layer that works with Xbody Newave and DryTech EMS systems, as well as other wired and wireless EMS vest systems. It is not an official Xbody product and is not affiliated with or endorsed by Xbody.
What is included in one set?
One short-sleeve top and one pair of knee-length shorts. The training vest, electrode pads, powerbox and any machine or tablet are not included.
Why do you dampen the underwear before a session?
The lyocell-blend fabric absorbs and holds water, and that moist layer conducts the stimulation from the vest electrodes to the muscles. Spray the contact zones with clean tap water until damp; if a spot feels like pinching or stinging mid-session, it has simply dried out — dampen it again.
What is the fabric made of?
47% lyocell, 44% polyamide and 9% elastane — a soft, four-way-stretch knit. It contains no silver or metallic fibers; conductivity comes from the moisture held in the lyocell, not from coated fabric.
Can it be washed after every client?
Yes. Machine or hand wash in cold water with mild detergent, then air dry in the shade. Tumble drying, ironing and bleach shorten the garment's life and should be avoided.
Which size should I choose?
Sizes run S to XXL for heights from about 155 cm to 185 cm — see the size guide above. If your height falls between two sizes, choose the larger one.
Does it work with wired (cable) systems too?
Yes. The underwear sits under the vest the same way regardless of how the vest connects to the powerbox, so it works with both wired and wireless setups.
Do you offer bulk pricing or custom logos?
Yes. Studios and distributors can contact us for bulk pricing. Custom logo printing is available on bulk orders; customers must provide artwork they have the rights to use.
How long will it take to receive my order?
All orders are processed within 3–7 business days (most in-stock items are typically dispatched within 1–3 business days). Estimated delivery times vary by shipping method:
- Standard Shipping: 12–20 days (taxes included on most routes — check at checkout)
- Expedited Shipping: 7–15 days (DHL, UPS, FedEx, TNT, ARAMEX) — ⚠️ (you pay import taxes)
- Sea or Rail Shipping: 40–60 days ocean transit + 5–10 days local delivery (taxes included)
- Air Shipping: 5–8 days air transit + 5–10 days local delivery (taxes included on most routes — check at checkout)
Your shipping method is marked at checkout: "(taxes included)" means the price you pay is final — sit back and wait for delivery, nothing else to handle. "(you pay import taxes)" means any import taxes charged by your country on arrival are yours to pay — these are collected by your country's customs, not by us.
⚠️ Please double-check your shipping method before ordering. If it says "(you pay import taxes)", those charges are your responsibility — we can't accept disputes or refund requests for import taxes on methods that don't include them.
How to track my order?
Once your order is dispatched, you'll receive a tracking number by email. You can track it anytime on our tracking page: 17track.net — just enter your tracking number there.
- If your order was just dispatched, it may take 1–2 days for tracking information to show up in the system.
- For Sea or Rail Shipping, tracking may pause during the ocean leg — usually 40–60 days — and resumes once the parcel reaches your local courier.
