Since men's ice hockey is a full contact sport, body checks are allowed so injuries are a common occurrence. Protective equipment is mandatory and is enforced in all competitive situations. This includes a helmet (cage worn if certain age or clear plastic visor can be worn), shoulder pads, elbow pads, mouth guard, protective gloves, heavily padded shorts (also known as hockey pants) or a girdle, athletic cup (also known as a jock, for males; and jill, for females), shin pads, skates, and (optionally) a neck protector.
Goaltenders use different equipment. With hockey pucks approaching them at speeds of up to 100 mph (160 km/h) they must wear equipment with more protection. Goaltenders wear specialty goalie skates (these skates are built more for movement side to side rather than forwards and backwards), a jock or jill, large leg pads (there are size restrictions in certain leagues), blocking glove, catching glove, a chest protector, a goalie mask, and a large jersey. Goaltenders' equipment has continually become larger and larger, leading to fewer goals in each game and many official rule changes.
Ice hockey skates are optimized for physical acceleration, speed and maneuverability. This includes rapid starts, stops, turns, and changes in skating direction. In addition, they must be rigid and tough to protect the skater's feet from contact with other skaters, sticks, pucks, the boards, and the ice itself. Rigidity also improves the overall maneuverability of the skate. Blade length, thickness (width), and curvature (rocker/radius (front to back) and radius of hollow (across the blade width) are quite different from speed or figure skates. Hockey players usually adjust these parameters based on their skill level, position, and body type. Most skate's width are about an 1/8 of an inch (3 mm) thick.
The ice hockey stick consists of a long, relatively wide, and slightly curved flat blade, attached to a shaft. The curve itself has a big impact on its performance. A deep curve allows for lifting the puck easier while a shallow curve allows for easier backhand shots. The flex of the stick also impacts the performance. Typically, a less flexible stick is meant for a stronger player since the player is looking for the right balanced flex that allows the stick to flex easily while still having a strong "whip-back" which sends the puck flying at high speeds. It is quite distinct from sticks in other sports games and most suited to hitting and controlling the flat puck. Its unique shape contributed to the early development of the game.
