Do not order if you have a large head!
I really appreciated being able to get a whole bunch of masks to try on, which saved me a lot of money and time and, probably, frustration. But I have a large head and sadly, most of the masks in the sample kit were too small, and the few that covered enough of my face were almost all too tight. (I mean, I know a mask has to fit snugly, but there's a difference between tight and "instant headache tight," if you know what I mean.
Since I prefer headloops, I let my mother, who has a smaller head, try on the earloop styles, and unfortunately she wasn't comfortable with any of them.
That said, the ACI duckbill mask included in the sampler did fit me, and in late February 2024, it was on sale, so I ordered two boxes, which will hold me for some time since I only leave home every 4 or 5 days.
Again, a good idea to offer a sampler, not Armbrust's fault I have a big head!
