Our Bluestar Flip-up Face Shield ships totally flat and assembles in seconds with 2 white plastic snaps. Anti-fog coated both sides. Can be used indoors or outside.
Headband is adjustable with a velcro strap. Once fitted, you probably won't have to adjust it again.
Can be hand washed and reused personally as needed. Keep in mind the anti fog coating becomes less effective each time the visor is washed.
