Section 2: Equipment
The Sliotar (Ball) - Rule 4.4(i): The diameter of the sliotar, not including the rim (rib), shall be between 69mm and 72mm. Its mass shall be between 110 and 116 grams. The rim (rib) height shall be between 1.8mm and 2.6mm, and the rim (rib) width shall be between 3.6mm and 5.4mm. The thickness of the leather (chrome or synthetic) cover shall be between 1.8mm and 2.7mm and shall not be laminated with a coating greater than 0.15mm. Sliotars are approved for use only on the basis of compliance with standards and tests set by Central Council, and Approved Match Sliotars must carry the GAA mark of approval; annual independent testing verifies continued compliance.
The Hurley (Camán) - Rule 4.5: Hurleys shall only be approved for use based on compliance with standards and tests set out by Central Council. In Underage Hurling, up to and including Under 12 age grades, the use of metal bands on hurleys is prohibited unless the metal bands are taped over.
Helmet with Facial Guard - Rule 4.2(i): In all Hurling Games and Hurling Practice Sessions it is mandatory for, and the responsibility of, each individual player to wear a helmet with a facial guard that meets the standard set out in IS:355 (or a replacement standard determined by the National Safety Authority of Ireland). Such helmets shall not be modified from their original manufactured state in any circumstances. A Referee shall not permit a player to take the field, or continue playing, without this equipment; a failure to comply with an instruction to wear an approved helmet with facial guard is itself a Dissent infraction under Rule 6.2.
Team Colours and Jerseys - Rule 4.1: Club teams shall wear their registered distinctive colours in inter-club competitions, and County teams shall wear their registered distinctive colours in inter-county competitions; where there is a similarity of colours the teams change to alternative registered colours. In all games, the goalkeeper shall wear a jersey which is distinctive from both the goalkeeper's own team's and the opposing team's outfield colours.
Central Council adopts a Code for Playing Gear and Equipment, and only sliotars, footballs, and hurleys complying with the provisions of that Code may be used; Central Council may also approve the use of a smart chip for sliotar authentication purposes in specific official games.
