Hockey bags are used to store and transport a hockey player's equipment. Skaters put everything except their sticks in their hockey bags. Goalies put everything except their sticks and leg pads in their hockey bags.
There are different kinds of hockey bags. The most common type of hockey bag has a main compartment for the equipment, a side pocket for small items like hockey tape, and two straps used to carry the bag. Some bags have wheels and a handle, so that the heavy bag can be rolled rather than carried. Other bags are shaped like a backpack, and can be carried as such.
There are many different brands of hockey bags. A few brands are STX, Bauer, Warrior, Under Armor, CCM, and Vapor.
