What are the rules for camans, boots and other kit?

Under Byelaw 1.4 (and 4.2 for youth):

• Caman: the head must pass through a ring 2½ inches (6.3 cm) in diameter, and no plates, screws or metal of any kind may be attached to it or form part of it. A caman in a condition dangerous to other players may not be used.
• Boots: studs must be solid (leather, rubber, plastic, aluminium or similar). Metal-tipped studs are allowed if they are not pointed and have no sharp or ragged edges; any metal seat for screw-in studs must not be visible. Moulded studs are fine.
• Nothing dangerous: players must not wear anything dangerous to another player.
• Shirts: teams wear distinguishing colours, goalkeepers wear colours different from outfield players and the referee, and shirts are numbered to match the team lines.
• Shin guards: compulsory in all youth training, games and competitions, made of suitable material and secured in place. Coaches should encourage guards that protect both shins and ankles.
• Helmet and faceguard: compulsory for anyone under 25; players 25 and over may opt out by signing a liability waiver before the season.

The ball has a cork and worsted (or approved) core and a leather or leather-like cover, 19 to 20 cm in circumference and 70 to 85 g at the start of the game.
