The head scarves are designed to match the force's uniform
Avon and Somerset Police is issuing head coverings to its female officers so they can enter mosques.
The force says the move will help its officers respect Muslim religious customs while carrying out their job.
The garments, designed to match the force's uniform, were designed in consultation with Muslim groups.
Imam Rashad Azami, of Bath, said: "This will go a long way in encouraging a trustful relationship between the police and the Muslim community."
Mr Azami, director of Bath Islamic Society, said: "The police have been working closely with the Muslim community in the area on many levels for the last few years."
There are two versions of the head coverings, to match the black of a police officer's uniform and the blue of the Police Community Support Officer uniforms.
Both carry the force's crest.
