What kind of mask can I use during summer since it's getting too hot?

Im still trying to get used to wear a mask since I just had to go back to work and I was ok these days but when summer comes I know its gonna be hard, it will be way too hot to breathe on a mask...i felt it on friday. I work in a daycare...nobody seems to bother about wearing a mask or they wear it in their chin,I know its hard but I dont want to be the person to spread it..since you can have it even with no symptons...what can I do is there a material to keep you cool and at the same time block the droplets??? Idk
