Can I wear a face mask when defending a penalty corner?

Yes. Under NFHS Rule 1-6-5:

• Defenders may wear a penalty corner face mask. Since 2025, a smooth, rounded wire-caged mask is also allowed.
• Since 2020, a player may wear a corner mask instead of goggles while defending the corner.
• Take it off once the corner ends. If there's no suitable chance to remove it, you may keep it on while play stays inside the 25-yard area.
• Wearing the mask beyond the 25-yard area is a misconduct penalty.
• If the defense gets a free hit inside the 25-yard area (for example, after an attacking foul in the circle), the mask can stay on. Officials may ask players to remove masks if there's a stoppage before the corner sequence ends.
