Swiss Shield Ultima Arbour is our softest, most attractive EMF fabric for clothing with the best radio frequency / microwave radiation shielding characteristics.

This product is made from viscose, which is often touted as a sustainable alternative to cotton or polyester. It is also popular in the fashion industry as a cheaper and more durable alternative to silk. Often, it is used to create  drapey summer dresses, skirts, soft blouses, drapes and synthetic velvet.

Our Lyocell viscose fabric is highly breathable, even more than fabrics such as cotton.

It also has great moisture wicking properties, which will keep you dry, fresh and comfortable: an ideal fabric for summer.

What Is Lyocell Fabric And Is It Sustainable?

If you’re searching for the sustainable superstar of fabrics then Lyocell (and especially TENCEL™, more on that later) should be atop your list. However, its accolades go far beyond the realm of sustainability. Being silky smooth lyocell feels great against skin, drapes beautifully, is lightweight, highly breathable, antimicrobial, moisture wicking, and is wrinkle resistant. It’s little wonder why it has been hailed as a “miracle fabric”.

How Is Lyocell/Viscose Made?

Since lyocell is derived from cellulose (i.e. trees) it is both sustainable and organic, with the most common sources being eucalyptus, bamboo and beech. These are fast growing varieties that do not require irrigation or pesticides and are often grown on land that is otherwise unsuitable for alternative uses. After harvesting, the wood is chipped and immersed in a solvent to extract raw cellulose before being passed through spinnerets that elongate the fibers. These fibers are then washed, dried, cut, carded and spun into yarn which is ultimately woven into a fabric.

Soft, Elegant, Viscose Fabric, Designed For The Needs of The Chemically Sensitive

This premium fabric is the most compatible with an electromagnetic hypersensitive (EHS) and or multiple chemical sensitivity (MCS) person.


  • Breathable: Lyocell is highly breathable, even more than fabrics like cotton.
  • Fabric texture: Silky smooth, drapes well and is soft, lightweight, and comfortable against the skin.
  • Moisture wicking: Has great moisture wicking properties, which will keep you dry, fresh and comfortable. An ideal fabric for summer. 
  • Biodegradable: Lyocell is fully biodegradable as the manufacturing process is free from harmful by-products.
  • Durable: The fabric is strong, long-lasting and it does not wrinkle easily. 
  • Great for sensitive skin: The fabric does not rub or chafe and is ideal for those who suffer from eczema or dermatitis, or anyone who loves the feeling of silk. 
  • Antibacterial: Due to its capacity to manage moisture lyocell does not hold odours like performance activewear and thus it is suitable for multiple wears between washes, which saves water and energy.
