Knowing Water Polo Gears are Up-to-Code
How do I know my waterpolo gear is up-to-code?
Check with your coach and or refs.
It's rough but not more than any other sports. You'll get bruised and bashed, but you're not being slammed against the ground, or running head-on into another dude because you think your helmet will protect you (protip: it won't).
The only things I think there are strict rules for are caps, and you can find that stuff on the FINA site: http://www.fina.org/content/wp-4-caps-0
