So soccer headgear doesn't prevent concussions but is it still a good thing to wear? Like it still protects the head and brain some what? Smart idea?

Concussion. soccer head gear may have a slight protective effect, but there is little data about its effectiveness. Like football helmets, concussion can still take place, because the brain moves inside the skull during acceleration-deceleration events. Much evidence that heading the ball results in a fall off on intellectual performance during the season and an improvement after season ends.
