Real Relief From Real People
Tested my meter with the cap on and off in the same spot — the reading dropped instantly. That's when I stopped feeling crazy for believing my symptoms were real. My afternoon fog has noticeably eased after three weeks of wearing it during work hours.
Halo Cap · Columbus, OH
I was skeptical of every hat and pendant I'd already wasted money on. Started wearing Halo at my desk every day. Within a week the 3pm brain fog that used to wreck my afternoons was noticeably lighter. It's soft enough that I honestly forget I have it on.
Halo Cap · Nashville, TN
That was my biggest worry — that I'd look like I was wearing tinfoil. It just looks like a cap. My headaches near my desk, right under the WiFi router, have gone from near-daily to maybe once every couple weeks.
Halo Cap · Rochester, NY
Three years of being told my bloodwork was fine. Bought Halo mostly out of desperation. The ringing in my ears is quieter than it's been in a long time, and I actually feel more like myself day to day.
Halo Cap · Lake Tahoe, CA
Packing, driving, unpacking — my stress headaches usually flare up during big moves. Wore Halo the entire week and didn't get a single one. Ordered a second one so I always have a backup in the wash.
Halo Cap · Northern Minnesota
My family thought I was overreacting about the new smart meter. I started tracking my symptoms in a notebook and they dropped off within days of wearing Halo consistently. Soft interior, stays comfortable for hours.

Why It's Called Halo — And Why The Hat Says µW/cm²
A halo is a ring of protection — the idea of a shield surrounding your head is exactly what this product is built to do. That's the name.
The hat itself is stitched with µW/cm² — microwatts per square centimeter — the real scientific unit EMF meters use to measure power density. It's not a made-up logo. It's the actual number staring back at you every time you check your exposure.
"Unplug Waves. Calm Minds. Squared Protection."
Every letter and symbol in that equation means something more to us:
Step back from constant signal, even for a few hours a day.
Less exposure, less noise, more room to actually think clearly.
Layered shielding, doubled down — never just one thin barrier.
Here's What To Expect After You Start Wearing Halo
Your Exposure Drops Immediately
No warm-up period, no charging, no activation — the shielding is physical, not electronic.
Take a reading with Halo off, then on, in the same spot. Most people see the number drop in real time.
Cumulative symptoms usually take a few days of reduced exposure to start easing.
The Fog Starts To Lift
Many customers report noticeably clearer thinking during the hours they'd normally hit a wall.
Especially near routers, laptops, and other high-exposure spots.
It stops feeling like "the hat" and starts feeling like part of your day.
Consistency Sets In
Customers who wear Halo consistently report fewer of the sharp afternoon crashes.
Especially for people who spend hours near routers, laptops, and monitors.
Not gone for everyone, but many report it's noticeably less present.
Protection Becomes Routine
Most long-term customers just grab it on the way out the door — no extra thought required.
No spraying, no replacing every 30 days — just wear and wash as normal.
The dread of "what will today feel like" starts to fade into the background.
The Shielding Inside Every Halo
One thin layer of metal can leave gaps. Halo's construction is layered specifically so there's nowhere left for signal to slip through.
Silver-Fiber Mesh
A woven conductive layer that forms the core barrier against WiFi, 5G, and Bluetooth frequencies.
Copper Thread Grid
Woven through the mesh to help disperse and redirect signal instead of letting it pass through.
Nickel-Coated Lining
Widens the range of frequencies covered beyond what a single-metal fabric can block alone.
Triple-Layer Weave
Dense construction with no seams or thin spots where signal could otherwise leak through.
Cotton-Blend Shell
Looks and feels like a normal cap — soft, breathable, no one can tell it's doing anything.
Full-Spectrum Coverage
One metal alone leaves gaps in frequency and coverage. Layered together, there's nowhere left for signal to get through.
Comfortable Enough
To Forget You're Wearing It.
You shouldn't have to choose between protection and comfort. No itchy metallic liner against your scalp. No bulky, stiff shape that gives it away. Halo is built to be worn all day, every day, without ever feeling like "the shielding hat."
