The SYB Wrist Band protects you by using real, science-backed technology woven directly into the fabric:

How It Works

• The band is made with 90% pure silver fibers that act like a miniature Faraday shield.

  These conductive threads block up to 99% of smartwatch EMF and 5 G radiation, including Wi‑Fi and Bluetooth, keeping it from reaching your body.

• Because it shields your body—not the device—it won’t weaken your watch’s signal or battery. Instead, it prevents the EMF from penetrating through your skin.

What to Expect

• Stop EMF from reaching your wrist and arm skin—significant reduction (lab-tested up to 99%, even 40 GHz 5G).

• Wear it under your smartwatch, just like a standard band—comfortable, breathable, machine‑washable (cold water, air dry).

• Note: The band will block all biometric functions (heart rate, wrist detection, etc.) of your watch—so those features won’t work while wearing it.

Simple Usage

1. Choose your size: Regular (~17 cm) or Small (~16 cm), both 5 cm wide—wide enough to fully cover most smartwatches  .

2. Wear it under your watch like a normal band.

3. Disable “Wrist Detection” on Apple Watch if needed to keep it active while wearing  .

4. Machine-wash as needed; keep it clean and functional .

Why It Matters

The SYB Wrist Band offers focused protection exactly where the watch sits—right over your wrist—without impacting how the watch connects.

If you often wear your smartwatch, this is one of the most effective ways to reduce direct EMF exposure from it.

Summary

The band’s silver-fiber weave creates a reliable shield that blocks up to 99% of EMF, fits comfortably under your smartwatch, and preserves device connectivity—though biometric features won’t work while it’s worn.
