Modern RF shielding apparel for everyday use. Our EMF Cap is a high-performance Faraday hat designed to add a conductive shielding textile layer around the head area for 5G, cellular, and wireless-frequency use cases.
Hand wash carefully in cold water. Use neutral detergent. Do not iron the silver lining.
Important: These products are technical textile products. Selection should be based on material construction, coverage, fit, frequency range, and available test data. They are not medical devices.
Putting a phone inside a hat gives a yes-or-no connection result. It does not measure how much RF energy passes through the lining. A call may still connect through the open side of the hat or with only a small remaining signal, so this test cannot confirm—or disprove—the hat’s attenuation.
Use a stable external RF source and keep the source, distance and orientation fixed.
Record a baseline reading, then place the hat over the same meter position without changing the setup.
Repeat the comparison from several directions and compare the relative change—not simply whether a call connects.
The silver-fiber lining acts as a passive conductive layer. It can reflect and attenuate part of the RF energy arriving from the directions it covers. Real-world performance depends on the material, frequency, fit, coverage, seams and openings.

Partial, directional attenuation—not a sealed enclosure or total isolation.
Performance depends on material, finished construction, fit, coverage, seams, openings, frequency range and test method. This product is a technical textile product, not a medical device, and is not intended to diagnose, treat, cure or prevent disease.
Shielding headwear combines conductive textile layers with thoughtful coverage and construction to create a wearable shielding solution.
The outer fabric provides comfort and appearance, while the conductive textile layer creates the shielding structure.
Different headwear shapes provide different coverage. Construction, fit and conductive area all influence the final design.
Different constructions balance coverage, warmth, fit and everyday wear differently.
A familiar everyday profile with a silver-fiber lining across the crown.
Soft, close-fitting coverage designed for comfortable everyday wear.
A warmer outer construction combined with a conductive textile lining.
Designed with a wide brim and conductive shielding fabric for broader head coverage in outdoor and everyday settings.
