I have a few cloth masks made by small makers but I find I can't wear them for more than a couple of hours. At work I wear the blue disposable ones because I find them easier to breathe in and I can tolerate them for longer. However, I feel bad about the environmental impact. Also, I am job hunting so I think I need something a bit smarter to wear for potential in-person interviews. What reusable mask brands would you recommend that are comfortable and breathable enough to wear all day?
