I am an adult who likes the Harry Potter world, and thus I searched for the Quidditch goggles. This brand is durable and the size is adjustable to fit anyone's head. The materials look like leather and strong plastic (though the buckle slide and the snitches on the sides are metal), and the clear lenses have 100% UV protection as a bonus! They seem only slightly oversized compared to the ones in the movies, but they are fun to wear nonetheless. I wear them almost every day, tipped up over my head instead of my eyes. People who don't know much about Harry Potter seem to think they are merely Steampunk goggles or something for flying an old-style plane. Very fun!
