The price of the caps soared 30% in a year to more than 2,000 pounds ($2,600) apiece for the hats made of black bear fur, the Ministry of Defense said in response to a freedom of information request by People for the Ethical Treatment of Animals.

“Stop wasting taxpayer pounds on caps made from slaughtered wildlife and switch to faux fur today,” the group said in a statement.

A luxury fake fur maker has offered to supply the army with free faux bear fur for 10 years, PETA said.

The military said it was open to exploring alternatives if they pass muster in durability, water protection and appearance. But “no alternative has met all those criteria to date,” a ministry spokesperson said in a statement.

The distinctive tall black hats, worn by guards in bright scarlet tunics, are seen by millions who watch the regular changing of the guard ceremony at the palace. They also appear at other royal events including the annual Trooping the Color ceremony honoring the monarch’s birthday in June.

The cost of the caps rose from 1,560 pounds ($2,035) each in 2022 to 2,040 pounds ($2,660) in 2023, the ministry said. More than 1 million pounds ($1.3 million) was spent on them in the past decade.

The price went up because of a contract change for fur that comes from bears killed in licensed hunts in Canada, the military said. Each cap requires one bear pelt, PETA said.

PETA, hich has been pushing for more than two decades to scrap the fur hats, said each cap requires one bear pelt. The group claimed that the defense department is propping up the “cruel” Canadian bear-hunting industry.

The ministry denied that charge and said if it stopped buying the pelts, it would not reduce the numbers of bears being killed.

Parliament debated the issue in July 2022 after an online petition with more than 100,000 signatures called for using fake fur in the caps.

“This hunting involves the violent killing of bears, with many bears being shot several times,” Martyn Day, then a Scottish National Party member of Parliament, said at the time. “It seems undeniable, therefore, that by continuing to purchase hats made from the fur of black bears the MOD is funding the suffering of bears in Canada by making the baiting and killing of those animals and the sale of their pelts a profitable pursuit for the hunters.”

Day said a poll at the time found 75% of the U.K. population found real bearskins were a bad use of taxpayer money and supported replacing the hats.

He noted that the late Queen Elizabeth II had ceased buying fur for her wardrobe.

Earlier this year, Queen Camilla, wife of King Charles III, pledged to buy no more fur products.
