Frequently Asked Questions
Fit & Compatibility

Comfort & Daily Wear
No. The Halo is a slim bumper, not a bulky case. The felt-lined interior sits flush against the watch, so it feels close to wearing the watch bare.
Yes. It's lightweight and the soft silicone and felt lining are comfortable for overnight wear.
Yes. The Halo is made from skin-safe, non-toxic silicone with a soft felt lining. It's designed for all-day, direct skin contact.
Performance & Sensors
No. The Halo is a slim bumper, not a bulky case. The felt-lined interior sits flush against the watch, so it feels close to wearing the watch bare.
No. Motion, GPS, and safety features are unaffected.
Yes. The charging area stays exposed and works with standard Apple Watch chargers.
No, it does not. The touch, swipe, and Digital Crown features all function normally.
EMF & Shielding
The shielding layer sits between the back of the watch and your wrist, where your skin is in constant contact with the device. It attenuates RF energy on that wrist-facing side while leaving the outward antennas clear, so Bluetooth, Wi-Fi, and cellular keep working.
Yes. The Halo isn't designed to eliminate all EMF or block every direction. It targets the wrist-side of the device, the point of constant body contact, and reduces RF exposure there. That specific, measurable reduction is what the independent SAR lab testing reflects.
It was independently measured at an FCC-accredited SAR lab, the same type of facility that certifies iPhone, Galaxy, and Motorola devices. The figure refers to RF energy on the wrist-facing side under controlled conditions. Results vary by device model and usage.
No. The shielding is a built-in material layer, not a coating or battery. It doesn't degrade with use or "run out" over time.
No, and we don’t claim that. Apple Watch meets regulatory exposure limits. The Halo is for people who want to reduce their RF exposure at the skin as a personal precaution.
Durability & Care
The Halo is made from durable silicone built for daily wear. With normal use it holds up to workouts, sweat, water, and everyday handling without degrading.
Yes. The Halo's silicone is fully water-resistant and built for workouts, sweat, and showers. Just check that your specific Apple Watch model is created for water exposure too, since water resistance varies by model.
Rinse it under water and air dry.
