What penalty corner kit can defenders wear, and when must they take it off?

Allowed (FIH Rule 4.2):

• Face mask (strongly recommended when defending a corner or stroke): smooth, preferably transparent or one colour, or a metal grill mask that follows the face. Protective headgear isn't allowed at any other time, except for assessed medical reasons.
• Knee pads and leg protection when defending a corner. Knee pads worn outside the socks must be exactly the sock colour or black.
• Hand protection that fits, without compressing, into an open-ended box 290 x 180 x 110 mm.
• Players must not use their protection to play dangerously.

Taking it off (Rule 13.3 n, revised for 2027):

• Remove it safely and as soon as possible after the corner is completed. Removing it before completion is allowed if done safely, but not recommended.
• If there's no suitable chance, players may keep it on, but must not take part in play outside the 23-metre area they're defending while wearing it. (The offence is now playing while wearing it, not simply leaving the 23-metre area.)
• When the attack plays the ball over the back-line or side-line, or the defence gets a free hit, defenders still wearing kit must remove it. The only exception: a player may immediately pass while wearing it, from within their defending 23-metre area. After that, nobody wearing the kit may play until it's off.
• Breach: free hit to the opponents outside the circle, penalty corner inside it (or a more severe penalty if the action deserves it).
• Ball hits discarded kit: free hit outside the circle; penalty corner inside it, or a penalty stroke if it prevents a probable goal.
• Thrown kit that hits an opponent, an umpire or anyone off the field on or above the knee (normal stance): the thrower must get a yellow card. Restart with a free hit if the ball was outside the circle, or a penalty corner (stroke if Rule 12.4 applies) if inside.
