it’s very protective. If I bump against something, it doesn’t just fall off. I like that these grip your lenses. No matter what happens, it doesn’t fall off! Nothing can get in it. If I’m shooting in sand, dirt, or dust, nothing can get in there.
I love that it’s universal. It’s so nice for travel. I don’t have to pack every single little lens cap for each lens. I keep better track of them and it keeps my lenses protected throwing them in and out of bags
