Ice, and lots of it. And not the crushed ice that you get at your local convenience store, either.

Ah, perfect.

Gloves and padding. Because ice is hard and very cold.

Hockey stick and puck. Games would be awfully boring without these.

Ice skates. You ever try skating across ice with shoes? It doesn't end well.

Masks for goalies. Gotta protect that punim. Also, they can make excellent Halloween costumes.
