The breathable face masks are designed to be used by people wanting to reduce their risk of getting or spreading coronavirus. In numerous countries wearing a face mask is recommended by governments for people when venturing out in public.
"As lockdown measures begin to gradually ease up and we look to leaving our homes to reconnect with our teammates, we want to help," said Adidas.
"Whilst not medically graded, it's designed to help prevent the spread of transmissible viruses and germs, to help protect those around you."
The masks are available to purchase in Europe, North America and China, with part of the sale price being donated to Save The Children's Global Coronavirus Response Fund.
"Last month we started reallocating design and supply chain resource to create reusable Face Covers. We're adding them to our range from this week – and in the UK, £2 from every pack of three purchased is donated to Save The Children's Global Coronavirus Response Fund."
Each Face Cover is made from Adidas' Primegreen material, which it describes as a high-performance recycled fabric free from virgin plastic.
The simple masks have tow loops to hook over a wearer's ears. They are designed to be reused and have the words "Wash. Dry. Reuse" printed on them.
The face masks form part of Adidas' response to coronavirus, which is branded #hometeam. Initiatives included in the response are creating face shields for US healthcare workers and its #hometeamheroes challenge, which donates $1 for every mile clocked using Adidas' training and running apps.
Wearing face masks is considered an important way for people to limit the spread of coronavirus. In the UK celebrities including Stephen Fry and Elizabeth Hurley modelled face masks designed by Ron Arad that are being be sold to raise money for the UK's National Health Service, while Standard Issue has created an open-source design for a face mask that can be CNC-cut.
