Take less, give more.  

At Virustatic SHIELD, we have always used natural and biobased fibres for their inherent technical capabilities. Biomimicry (taking inspiration from the wisdom of nature and the natural world) is at the heart of all our product developments and technologies. 

Merino is a 100% natural, renewable, and biodegradable fibre. Merino is grown year-round by happy and healthy Merino sheep, and our merino is guaranteed by RWS (Responsible Wool Standard) Certification to be ethically raised.  

 This product, developed by Virustatic® is safe to be worn next to the face, nose and mouth.  

Many competitor brands use polyester or recycled polyester which is created from fossil fuels. These materials contain BPA, PFAS/PFOS and toxic forever chemicals, they shed toxic microfibers, and takes more than 500 years to decompose. We say “competitor brands”, but there is no competition or comparison. 

We recommend that you always choose biobased or natural fibres to be worn next to your skin, especially the face, nose and mouth. 

Some standout features: 


MERINO SHIELD fibres hold up to 30% of their weight in moisture without feeling wet (most fabric can hold only 5%), while simultaneously wicking away moisture from the body. So, no matter how hard you are walking, climbing, talking, or scrambling, the material remains dry and comfortable. 



Virustatic’s MERINO SHIELD® material fibres move sweat and liquid away from your skin, and they capture bacteria, preventing it from mixing with the air and giving off a smell. 



Merino helps you stay “just right” no matter the weather or level of exertion. The natural crimps and bends in the fabric act as insulation, stabilising your baseline body temperature so you don’t get too hot when it’s hot or too cold when it’s cold. 



Our MERINO SHIELD knit has give, but its corespun technology means it holds its shape and is durable; our MERINO SHIELD® moves with you and our ultrafine micron diameter yarn means it is superbly comfortable for very long wear. 



Our products were designed to protect you anywhere – from trains and airplanes to marathons to mountain climbs.
