Protection from NASA space suits

Lambs' Faraday Long-sleeves T-shirt is the first garment to get inspired by NASA space suits technology. Since astronauts traveling in space are over-exposed to radiation (up to about 4,000 chest X-Ray per trip), space suits were designed to be radiation-proof. We took the same technology, and integrated it in the perfect Long-sleeves T-shirt: soft, lightweight, breathable, antibacterial, UV blocking. Lambs’ radiation-proof technology is tested in military grade laboratories.

The mechanism of radiation protection

Our technology uses the principle of electromagnetic shielding. Radiation cannot reach an object that is fully covered by a tight conductive grid, as it cannot pass through holes in conductive materials that are smaller than its wavelength (picture elephant trying to pass through the holes of a fence). We seamlessly integrated a close-knit of conductive silver fibers all around our Long-sleeves T-shirt and created an advanced electromagnetic shield to protect your body blocking 99% of wireless radiation.

Pure Silver Lining

Each Faraday Long-sleeves T-shirt is embedded with a full layer of Silver Flex Fibers. We chose silver because it is one of the most conductive materials known to earth. It is a noble metal – like gold or platinum – that has been used for thousands of years for medicine and tissue healing. While each fiber is smooth, flat and soft to the touch, the silver cannot be scratched off or washed out. It is toxic-free and hypoallergenic.

Extremely soft fabric for optimal comfort

We wanted a technological Long-sleeves T-shirt that truly feels amazing to wear. Our fabric uses Silver Flex Fibers in combination with XSoft Cotton. The mix is incredibly breathable, it allows sweat and moisture to be quickly released, and is 50% more absorbent than cotton. This combination makes the Faraday Long-sleeves T-shirt incredibly soft, dry and comfortable all day.

Anti bacterial and “stink-free”

Lambs' Faraday Long-sleeves T-shirt has been created with the active man in mind. Bacteria are the origin of sweat odors, so we have designed this Long-sleeves T-shirt to be antibacterial. The shirt’s silver fibers tackle bacteria at the molecular level by destroying their cellular structures and preventing them from developing, multiplying and creating odors. Wearing the Faraday Long-sleeves T-shirt is not only hygienic; but also a huge confidence booster.

Heat Regulating technology

Lambs' Faraday Long-sleeves T-shirt was thoughtfully designed to bring you the best temperature regulation possible. It will keep you cool in the midst of high activity, and warm otherwise. The powerful heat-regulation properties of Silver Flex Fibers combined with breathable XSoft Cotton work together to limit formation of hot spots on your body such as below your armpits. The Faraday Long-sleeves T-shirt maintains you at the ideal temperature.

UV Protective

We want you to be able enjoy an active, outdoor lifestyle, so we designed Lambs' Faraday Long-sleeves T-shirt to be UV protective. The dense tight mesh of its Silver Flex Fibers minimizes the amount of UV light that can pass through. The Long-sleeves T-shirt composition is ideal for disrupting UV light, and its black color makes is highly effective at absorbing UV rays. Lambs covers you from ray damages both from the wireless radiation and sun rays.

Wrinkle free & machine washable for low maintenance

You won’t need to worry about ironing, shrinking or color loss. The WaveStopper fabric of this Long-sleeves T-shirt is wrinkle resistant and nearly crease-free. It maintains the shape and keeps the color vibrant, wash after wash. The Faraday Long-sleeves T-shirt is perfect for traveling or minimal at-home care.

Breathable and lightweight

Lambs' Faraday Long-sleeves T-shirt is breathable and also hydrophilic, meaning that it will soak up sweat on its surface and allow it to evaporate quickly, so you stay comfortable and dry. Its soft, silky and weightless fabric makes it the ideal essential for all-day wear. Long-sleeves T-shirt weighs only 4.7 ounces, so you benefit from all this technology while feeling light and free.
