¹ A peer-reviewed experiment measured 53 dB at 1.5 GHz on a copper/nickel-coated polyester textile specimen. At a tested frequency, 20 dB and 40 dB mean 99% and 99.99% less RF power transmitted through the tested material. RADIHALT uses a copper/nickel conductive inner layer; real-world results depend on coverage and setup. Cu/Ni textile experiment (Polymers, 2021).
Construction
Two layers, stitched and bound together. No batteries, no electronics and nothing to charge.
The side you touch. Soft, breathable and familiar, so it feels like a throw rather than equipment.
A woven conductive textile that reflects and absorbs radio-frequency energy along the path it covers.

Everyday use

Lay it across your lap and put a suitable hard support above it for the laptop. Keep the laptop's vents and cooling surface clear, then check that wireless connections still work as intended.

Use it as a mat when you want a conductive layer between a wireless device and the area underneath. The open sides remain unshielded.

Position it between a router and a specific area you want to shield. Do not drape fabric over the router, block ventilation, or assume whole-room reduction.

Fold the blanket for travel and lay it across a suitable desk or lap setup. The larger 36 × 30 inch size covers a wider work area.
