Ds about to start 6th form next week. With news tonight that he might need facemarks, I am trying to get prepared. He takes public transport to get there so will need masks anyway, but I am thinking about a bag to put the mask into so it is not just shoved in his school bag or pocket. Potentially he might need two masks a day, so two bags. I don't want to use ziplock bags as we would need to throw away and replace each day. So is there a washable version that I can just wash with the masks at the end of the day???
