    Mask

    A diving mask is used for several reasons
    Players can equalise their ears using the Valsalva manoeuvre as the nose is covered Unlike swim goggles a mask sits outside the eyes orbit, reducing the effects of any impact on the mask Improved underwater visibility
    A low volume mask with minimal protrusion from the face reduces the likelihood of the mask being knocked, causing it to leak or flood and temporarily blind the player. In line with the rules any masks must have two lenses since a single lens mask poses a significant safety hazard in the event that an unfortunately placed puck should hit and possibly pass through the lens. A variety of webbing strap designs are available to replace the original head strap with a non elastic strap that further reduces the chances of the player being de masked.
