The trucker hats featured the words "No hate in our state" and symbols for male, female and transgender.

The girls asked fans to wear the gifts with pride as a thanks to the band for not joining the likes of Bruce Springsteen, Pearl Jam, Ringo Starr, Nick Jonas, Demi Lovato, and Maroon 5, and cancelling state shows.

Many acts have boycotted North Carolina in recent months in protest of controversial legislation dubbed the 'Bathroom Bill', which requires people using public bathroom facilities use the restroom corresponding to their gender assigned at birth.

When fans arrived at the two Dixie Chicks shows in the state over the weekend (12-14Aug16) they were handed the free trucker hats.

Singer Natalie Maines told the Raleigh crowd on Friday night, "We have a favour to ask: Since we didn't cancel our show - you're also the only state we bought gifts for - could you pull out the hats that we gave you, because we love to support positivity. Peace and love."
