Faraday™ Cap

Protect your brain from EMF. Silver-fiber technology that blocks over 99.7% of EMF (cell phone, WiFi, Bluetooth radiation) and supports your cognition.



Our brains are increasingly challenged by the EMFs that permeate our environment. The Faraday™ Cap is designed with WaveStopper™ fabric to block over 99.7% of EMF radiation. The World Health Organization, NIH, and CDC have drawn attention to the potential impacts of EMFs on brain health, including brain cancer, memory and cognitive problems, brain fog, and increased risks of neurological disorders such as Alzheimer's and Parkinson's. The Faraday™ Cap provides an essential shield, aiming to boost brain function and health. Slip on the Faraday™ Cap for a smarter approach to everyday life in the digital age.

This Cap is super comfortable and perfect for everyday wear. The inner 360º silver lining protects you from 99% of exposure to wireless radiation. Soft, lightweight, breathable, antibacterial, and anti-odor, this Cap integrates the ultimate protection without sacrificing on comfort.

Yup. We know. It’s not cheap. So what makes Lambs more expensive than your average big bucks store garment?

#1, the fabric. Our proprietary fabric uses over 40% of silver fibers and cost the same to produce as cashmere. This is not counting the R&D cost in order to make it soft and cozy.

#2, the manufacturing. We care about making the most premium, high-quality clothing on the planet. That means we partnered with a factory that pays equitable wages, fair time-off, and who is certified OEKO-TEX - then highest environmental rating. That means that we pay a ~30% premium on manufacturing - and we wouldn’t want to have it any other way.

#3, the quality-control. You trust us with your long-term health. We take this seriously. That means that we have increased quality control to ensure every production batch is respecting our highest quality standards.

All in, our cost of production is ~10x that of a normal, equivalent piece of clothing. Now, we could (maybe) do it without #2 and #3 to shave a few dollars off. But it wouldn’t be right. It wouldn’t be Lambs. Our commitment? With us, you will always get what you pay for.

WaveStopper™ Technology

WaveStopper™ is the world’s first radiation-proof fabric technology for regular garments. WaveStopper™ uses a proprietary concept that includes a tight mesh of SilverFlex™ fibers carefully woven to create an electromagnetic shield. The conductivity of SilverFlex™ mesh cancels out the magnetic field of EMFs and as a result reflects the radiation outside the garment. WaveStopper™ is tested in military-grade laboratories and certified to be blocking over 99% of EMFs including cellphone, 4G, 5G WiFi, and Bluetooth radiation.

UV protective

Lambs is all about protecting your health from external environmental factors you can’t control. In addition to protecting you from wireless radiation, the Faraday™ line is designed to be UV protective for ultimate protection. The dense, tight mesh of the X-Soft™ Silver fibers minimizes the amount of UV light that can pass through.

Antibacterial and “stink-free”

Lambs' Faraday™ line has been created with the active person in mind. Bacteria are the origin of sweat odors, so we have designed Lambs to be antibacterial. The X-Soft™ Silver fibers tackle bacteria at the molecular level by destroying their cellular structures and preventing them from developing, multiplying and creating odors. Wearing Lambs is not only protecting your health, but is also optimally hygienic.
