Equipment
The hard surfaces of the ice and boards, pucks flying at high speed (over 160 km/h at times), and other players manoeuvring (and often intentionally colliding) pose a multitude of inherent safety hazards. Besides skates and sticks, hockey players are usually equipped with an array of safety gear to lessen their risk of serious injury. This usually includes a helmet, shoulder pads, elbow pads, mouth guard, protective gloves, heavily padded trousers, a 'jock' athletic protector, and leg guards. Goaltenders wear masks and much bulkier, specialised equipment designed to protect them from many direct hits from pucks.
Youth and college hockey players are required to wear a mask made from metal wire or transparent plastic attached to their helmet that protects their face during play. Professional and adult players may instead wear a visor that protects only their eyes, or no mask at all; however, some provincial and state legislations require full facial protection at all non-professional levels. Rules regarding visors and face masks are mildly controversial at professional levels, as some players feel that they interfere with their vision or breathing and/or encourage carrying of the stick up high, in a reckless manner, while others believe that they are a necessary safety precaution.
