There are also special hockey water bottles with extra long straws to reach a player's mouth even while wearing a helmet.
Goalies often keep water bottles on the top of their net for easy access. There is a shelf in the bench area for skaters to keep their water bottles during a game. During a time-out or stoppage in play, most players can be seen drinking from their water bottles.
There are also options to buy a set of multiple water bottles at most of these sports stores, which is great for supplying a team with water bottles. Pure Hockey also carries water bottle carriers for multiple water bottles.
