Mission Darkness™ EMF Blackout Hat

The Mission Darkness™ EMF Blackout Hat is a comfortable shielded baseball style cap perfect for everyday wear. It's lined with a discreet layer of TitanRF™ Flex Faraday Fabric, an electromagnetic frequency (EMF) shielding material that has been lab certified to confirm shielding effectiveness standards IEEE 299-2006 (see report below). This material provides a barrier between your head and harmful electromagnetic radiation (EMR) and radio frequencies (RF) coming from mobile devices, cell phone towers, smart meters, and other outside sources. The hat is breathable, flexible, and uses an adjustable snapback closure that fits most head sizes from 21.5" to 23.6" (55cm to 60cm) circumference. Wear during travel, while on the phone, at a workstation, or any location where you want to reduce your exposure to EMF.

We included a faraday testing pouch constructed out of TitanRF™ Flex Faraday Fabric (the same shielding material used in the hat), so you can use the Mission Darkness app to test the signal blocking capabilities of the material yourself! A fully enclosed faraday cage (like the testing pouch) is required to perform the test. The hat ships is a deluxe resealable box, ensuring that it retains its structure while stored inside, and serves as a presentable gift box.

Why EMF Protection in a Hat?

As cell phone and electronic device capabilities increase, so does the amount of EMR/EMF they emit. Your daily routine likely has you exposed to staggering amounts of EMF, which can be absorbed through your body and harmful at certain levels. The truth is that the long-term effects of high frequency signal exposure, from sources such as 5G radiation, are still unknown because the general public has not been exposed to these types of frequencies for long periods of time. This is why so many people are incorporating shielded clothing, rooms, etc., into their lives—they would rather be safe than sorry.

We are doing our part to offer shielded solutions for this preventative measure. You cannot always control the radio frequency signals you come into contact with, but you can use barriers like shielded clothing to reduce your exposure. The high-shielding fabric used in this hat is backed by years of signal-blocking excellence.

Who Uses It?

Individuals react to EMF differently and some require protection from various frequencies that surround them in everyday life. The stylish and shielded hat is designed for individuals with EMF sensitivity, health concerns, as well as the growing population seeking to reduce their exposure to EMF/EMR. Little precautions, such as wearing shielded clothing, can make a big difference in EMF protection.

How Do You Know This Works?

Bonus Faraday Testing Pouch Included!

The package includes a faraday testing pouch constructed out of TitanRF™ Flex Faraday Fabric (the same shielding material used in the hat), so you can use the Mission Darkness app to test the signal blocking capabilities of the material yourself! A full faraday cage, like the pouch, is required to perform this test. Read the testing instructions for further details.

Scientifically Proven Performance — Lab Tested and Certified to Confirm Shielding Effectiveness Standards IEEE 299-2006

IEEE 299-2006 Keystone Compliance laboratory testing to confirm shielding effectiveness of Mission Darkness TitanRF™ Flex Faraday Fabric

Testing Completed by Keystone Compliance Laboratory on October 7, 2020

The TitanRF™ Flex Faraday Fabric lining the hat has been tested and certified to confirm shielding effectiveness standards IEEE 299-2006. The shielding effectiveness test was conducted by Keystone Compliance, a full-service regulatory compliance laboratory offering solutions for nearly all EMC/EMI, environmental, ISTA-certified package and ingress protection testing requirements.

IEEE 299-2006 is the standard test method for measuring the effectiveness of electromagnetic shielding enclosures and materials. The TitanRF™ Flex Faraday Fabric is advertised as a material that can be used to block the frequency range most mobile devices and electronics transmit/operate within. To provide validation for this claim, the shielding effectiveness test measured how well the fabric shields frequencies between 1.5GHz to 40GHz. The positive test results provides authentication of its shielding abilities. The full test report and signal attenuation graph can be viewed on the link below

EMF Radiation Shielding Apparel

Mission Darkness™ offers a growing line of EMF radiation shielding apparel and home interior products. The main function of the shielding apparel line is to offer a barrier between your body and harmful electromagnetic frequencies (EMF) and radio frequencies (RF) inside your home, office, and public places, such as those coming from cell phones, laptops, Wi-Fi routers, smart meters, 5G cell towers, and additional sources.

Similar to how our faraday bags block signals from penetrating, shielded apparel uses the same materials to prevent signals from reaching your body. Please note that blocking EMF requires the same materials (faraday fabric) as blocking signals, but not the same construction methods. To effectively block signals like cell and Wi-Fi, a fully enclosed faraday cage is required. This means you would need to COMPLETELY cover your body with fabric, with no openings, to block these signals from reaching you. It’s impractical to do this for daily life, so the next best option is to reduce EMF by covering vulnerable areas with the same materials. This hat includes faraday fabric that can completely block signals, but you cannot test this capability without a full faraday cage. For this reason, we included a testing pouch built with the same materials to demonstrate the signal blocking properties of the material in your hat.

Good item

It's for my own use


Works as advertised. Great fit.

Great product.

It works, but at the cost of being *very* uncomfortable.

I got this Mission Darkness hat to replace a cheaper EMF shielding hat that uses stainless steel. The Mission Darkness hat has the snapback closure, which is nice, but the inside of the hat has several hard spots that dig into your scalp. The pain caused by the hat doesn't compare to the pain caused by the half-dozen cellular antennas I work under, so there's that at least. Hindsight being 20/20 the beanie would likely be the more comfortable option for the head, but I live in the Texas heat so that's a no-can-do. The hat being solid black doesn't win any points in regard to the Texas heat either. I really wanted this Mission Darkness hat to become my go-to for EMF head protection because it is technically superior (to an almost unbelievable level, the testing pouch gave my Safe and Sound Pro II meter a >0.2uW/M^2 reading!!!), but at a comfort level I'll just have to go back to my old hat and that's all there is to it...


This is a well made hat. I will be buying more from Mission Darkness.

This is a very nice hat. I’ve had it a little over 2 months. I loved the packaging it came in. Really cool. You feel like you’re getting what you paid for. It really does block EMF and RF. Tried and true! Really good hat. Oh and I’ve never had so many people infer about an article of clothing before. A lot of people want to know “what’s mission darkness?” then I can talk about “””conspiracies””” with them. Yes it’s a real tinfoil hat and I’m wearing it. I love it. You guys have earned a repeat customer. All your gear looks sweet!

Very good

Very good quality very comfy a little expensive but you can’t put a price on protection.
