Big and lightweight. Would give it 5 stars if it had a nose wire and toggles on the neck strap.
I live in Japan, and I'm a big guy with a full beard. It has been a real struggle to find masks of any kind that fit me. even ones labelled as XL are laughably small.  I bought the XL version of this mask as a trial, and after wearing it for a couple of days, I immediately ordered 10 more., so I don't have to wash a single mask every night.  It is big enough to cover the entire lower half of my face, and rests comfortably under my jawline, containing my manly beard with ease haha. It is wide enough to reach my ears, and thanks to how the neck strap is designed, it makes the mask adjustable, so it can be tightened or loosened as needed. It is very soft  and double layered, with the inner layer acting as a filter pocket for extra protection if you want. But it doesn't feel heavy or restrictive to me. I only have two minor "complaints" First, as a glasses wearer, a nose wire would have been great to help keep my specs from fogging up occasionally. Though obviously that's not a problem for those with 20/20 vision. And second, a couple of small toggles (like those found on drawstring bags) to help keep the neck strap from loosening over time, would be great. Not a problem for general daily use, but I'm pretty active in my job, and had to tighten up the neck strap from time to time, to keep it as snug as I like.  However, I was easily able to fit my own nose wire and toggles in minutes, so it isn't a big deal. Just a minor "if I was making these I'd...." type complaint. Generally I'm very happy with the mask I bought. Mostly because I no longer look, or feel, like a dishevelled giant, with my beard pilling out from the edges of the tiny masks available in Japan. I am confident the further purchases will be just as good.
