As you stated, the Costume Guidelines say that full helmets are not allowed. Headwear may be worn as long as it does not cover the face and the eyes are visible. I asked a Cast Member about simply bringing the helmet into the event without donning it, as an accessory to your costume.

At Disneyland Resort, the policy regarding Mandalorian helmets is strictly dictated by the park's dress code for guests aged 14 and older. According to official rules, adults are prohibited from wearing masks of any kind, except for medical purposes. This means that while you can wear a Mandalorian-inspired outfit (often called "Disneybounding"), you cannot wear the iconic beskar helmet if it covers your entire face. For guests under 14, some masks are permitted as long as they provide peripheral vision and the eyes are visible, but full-head helmets are still generally discouraged. In 2026, security remains highly vigilant about this rule to ensure that all guests are easily identifiable and to prevent any confusion with official costumed characters in Star Wars: Galaxy's Edge. If you bring a helmet as a prop, you will likely be asked to carry it throughout the day or leave it in your vehicle. To capture the "Mando" look legally, most fans opt for a themed helmet-style hat or a headband that suggests the character's visor without actually obscuring their face.
