I've been an agency nurse in nursing homes since the outbreak. I compare wearing a mask in one of these facilities to standing in a sauna with a pillowcase over your head. Outside of an N95, this is the only mask I've worn since the outbreak.Good:1. The mask and ear loops are soft, leaving little to no ear or face marks after my 12-16 hour shifts.2. They are made of quality material; none of that irritating sweater-like nose and mouth lining.3. They provide a form-fit around the nose, face, and under the chin, but they're not hard to breathe in.4. I like the all black color.Dislike:1. The mask straps have popped off of several masks in my last box. I'm rough on my masks though.
