This is used without faceguard. I've measured it by the size of my head which is 56cm and I would say it's a medium. All the clips work fine Please note I'm not sure on the size and sold as is on the estimation on sizing. I think it's this model TT-32S but uncertain. There's some markings on the helmet as shown in pictures.
