The advice from the HSE on wearing face covering is as follows:
A cloth face covering should cover the nose and go under the chin and:
- fit snugly but comfortably against the side of the face
- be secured with ties or ear loops
- include at least 2 layers of fabric
- allow for breathing without restriction
Please see the Public Health advice on wearing face coverings which is available on the HSE Website (https://www2.hse.ie/conditions/coronavirus/face-masks-disposable-gloves.html#cloth-face-coverings).
