I stopped by the Visitor Center over Thanksgiving and found these masks. They are thick yet breathable. The metal at the bridge of the nose is a must for me. They have also washed up very well. Along with the mask I also bought a Best Friends lanyard and keep my mask attached to the lanyard. This way I haven’t lost a mask yet. After I’ve been in a store shopping, usually the first thing I need to do when I get out in fresh air is take off my mask and I can just drop my mask and not worry about dropping it or losing it before I can get it back in my purse. I’m actually on line to order some more!
