I purchased these masks after buying the regular Essential 3-layer mask (they didn't have these "Plus" ones at the time). I really liked the regular masks I received. The material is thick, but comfortable. The adjustable straps and nose piece really help the mask fit your face tightly, which is good for protection (on both the regular and plus editions). The only thing I wasn't a fan of on the regular mask was that with my long beard, it looked like a little hexagon on my face and kinda "beaked" out. With the plus masks, the nose is shorter, the sides are wider, and there is a small "lip" at the bottom that slides over your chin. I really like them, and wear them every day at work (I work on a University campus with a strong masking policy). I'm comfortable all day and I feel safe.
The only downside for me is that the bottom lip on the mask pushes my beard back towards my face creating a wavy like texture when I remove the mask. Not a big deal, but it does make me want to shave my beard.
Other people have told me that the mask is too thick for them, but I don't mind at all. I use a rescue inhaler for breathing sometimes (such as vigorous exercise or allergies), but these masks don't bother me at all.
I do wish the was bags had two snaps on them instead of one.
