Made in the USA · Full-Bed Panel
HexTex™ Core Plus
Better nights. American made.
The whole bed, one layer. HexTex™ Core Plus lies beneath your fitted sheet across most of a queen-size bed — for couples, larger frames, and anyone who moves through the night and wants the same fabric wherever they land. Soft organic cotton, a woven graphene pattern, and nothing to switch on.
Made in the USA
Made in the USA
American farms. American mills. American hands.
Most graphene apparel comes out of overseas supply chains. HexTex™ doesn’t. The cotton is grown in Georgia. The graphene goes in on the loom in North Carolina. Every panel is cut and sewn in Pennsylvania — by American workers, in American factories.
Full-bed coverage
Wherever you land, it’s there.
The HexTex™ Core covers the zone where your back and hips meet the bed. Core Plus stretches across most of the mattress — so side sleepers, stomach sleepers, restless sleepers, and both partners on a shared bed all rest on the same graphene-woven layer, in any position, all night.
One layer, one fitted sheet over the top, and the bed looks exactly the way it did before.
The physics
Your body is already a far-infrared source.
Every warm body radiates. Your skin gives off thermal energy all day and all night, peaking near 9.4 microns — squarely in the far infrared. You can’t see it, but you feel it any time you stand close to someone. Every fabric you sleep on trades some of that energy back and forth with you. HexTex™ adds something ordinary bedding doesn’t have: a woven network of graphene, a carbon material thermal engineers reach for when they want to manage heat.
Physics has a tidy rule here: a surface that absorbs far infrared well also re-radiates it well. Sitting close to your skin, the graphene weave takes in part of the warmth you give off and sends part of it back your way. No heater, no current, no added heat — just more of your own warmth kept close.
Why we built it
Better days start with better brainwaves.
Your brain runs on rhythms. Alpha waves (8–12 Hz) take over when you’re awake but at ease — eyes closed, mind quiet, the state that stress crowds out. Theta waves (4–8 Hz) rise as you drift from wakefulness toward sleep. Together they’re the brain’s downshift: the move from on to off.
They’re also the signature of stillness. Since the first EEG studies of yogis and Zen monks in the 1960s, researchers have found the same pattern again and again in people who meditate: more alpha as the mind settles, more theta as attention turns inward. It’s the state practitioners spend years learning to reach on purpose.
In 2022, a team at Zhejiang University put graphene against the back of the neck and watched on EEG. Alpha waves appeared 2.3× more often and lasted 2.9× longer. Theta waves appeared 3.0× more often and lasted 4.1× longer. The researchers attributed it to graphene’s far-infrared output lining up with the band human skin absorbs best.
Their version needed a power cord and 50 °C of heat. We wanted to know what graphene could do with no cord at all — running only on the warmth your body already gives off. That’s HexTex™.
Study used a powered graphene film heater, not HexTex™.
For athletes
Graphene, put to the performance test.
The closest published study to HexTex™ tested the same idea we built on: passive graphene fiber — no power, no heating element. In a 2025 double-blind trial in Sports Medicine – Open, active young men ran a treadmill test to exhaustion twice: once in graphene-fiber compression gear, once in identical gear without the graphene. Neither the runners nor the researchers knew which was which.
In the graphene gear, they went longer, and their heart rates ran lower at the same workload.
Same principle as HexTex™: graphene in the fiber, your body as the only source. Their fabric was a graphene-nylon compression knit. Ours is graphene woven into American cotton, built for the eight hours you spend off your feet.
15 participants. Study used graphene compression garments, not HexTex™.
Why not an electric pad
Warmth without the wattage.
Electric pads push heat on a dial and a timer. Your body, meanwhile, is running its own program — core temperature naturally drifts down as you fall asleep. HexTex™ adds no heat and has no controls. It’s a passive layer that works only with the warmth you already make — nothing to set, nothing to switch off at 3 a.m.
And because there’s no wiring, no current, and no electronics, HexTex™ is EMF-free by design — no electric or magnetic field under either of you, no wireless signal, and nothing to interfere with your phone, sleep tracker, or bedside devices.
Hot sleepers, read this
Warm science. Cool bed.
Most people sleep best in a cool room, and the last thing a hot sleeper wants is another warming gadget. HexTex™ isn’t one. Even across the whole bed, it’s a single thin layer of cotton under your fitted sheet — not a blanket, not a topper, not a heated pad — and it adds no heat of its own. Nothing in it pushes against your body’s normal overnight cool-down.
Keeping a little more of your own warmth close is a subtle effect — most people don’t feel it as heat at all. In early at-home use, only one tester mentioned sleeping any warmer.
From early testers
Early nights.
“Thank you for sending a sample and creating this product. … I’ve been really impressed with the effects, especially the overall calm and clarity. They are subtle, but they are there. I sleep with it under my pillow case and if I need a nap, I bring my pillow to the couch and I’m dozing off in no time.”
“I noticed that I fell asleep right away and when I did get up 7 hours later, I felt great! Energized and ready for that day. Normally I would wake up a couple of times during the night, but since using HexTex Halo I am experiencing deep peaceful sleep!!”
Personal experiences shared by early testers, not clinical results.
The fabric
Woven in. Not sprayed on.
Many “graphene” textiles are ordinary fabric with a coating or print on top. HexTex™ is different at the loom: the graphene goes in as part of the weave itself. Nothing printed, nothing coated, nothing to flake off in the wash.
- Organic cotton with graphene woven into the weave itself
- ~3 mm graphene stripe spacing vs. the ~4 mm industry standard
- Tight, low-lint weave built to hold its fibers
- Machine washable — soft on both sides, no wrong way to use it
- EMF-free — no wiring, no current, no electronics
- Grown in Georgia · woven in North Carolina · sewn in Pennsylvania
- Construction
- Fabric weight
- Air porosity
- Water resistance
- Static decay
No. It’s woven into the fabric on the loom in North Carolina — not sprayed, not printed, not a coating, not a loose powder. There’s no surface treatment to rub off on your skin or your sheets.
HexTex™ is a tight, low-lint weave built to hold its fibers, and the graphene is part of that weave — not a layer sitting on top.
It’s a cotton fabric: sleep warm, sweat on it, wash it, repeat. The organic cotton face is the side most people keep against their skin.
None from the product. No wiring, no battery, no chip, no wireless. The only energy involved is the infrared warmth your body gives off anyway.
Complete the bed
After the sauna, the bed.
If the evening sauna is where your day winds down, Core Plus is where the night takes over. Pairs with the HexTex™ Halo — pillow above, full panel below.

Good to know: HexTex™ is bedding, not a heating device. Keep it out of cribs and away from infants.
HexTex™ is a graphene textile designed for comfort and warmth, not a medical device. It contains no heating element and does not add heat. Published research on graphene far infrared describes other products used under different conditions and is not clinical evidence for HexTex™. HexTex™ is not intended to diagnose, treat, cure, or prevent any disease.
