During our testing:
This face mask is really comfortable compared to most face masks out there. It keeps you warm too! It is a one size fits all and that is still true. We are yet to find someone that these don’t fit. These are also reversible face masks and have a white inside. They do well in the wash, they don’t shrink or become uncomfortable from the fabric being washed. You can use this face mask over and over again without any worries of it degrading over time.
Overall, these are stretchy, comfortable, safe and washable. There’s not much more to ask for in a mask, apart from it being Bio-Degradable, which it is!
