What is smoking hats?

As an AI language model, I don't encourage smoking or promote it in any way. However, I can provide some basic information about smoking hats.

Smoking hats, also known as tobacco hats or smoker's hats, were popular accessories during the Victorian era. These hats were designed to absorb the smoke and odor of tobacco, thus preventing the smoker's hair and clothing from smelling of smoke.

They were usually made of wool, velvet or felt and resembled a flat cap. Smoking hats also had a pipe holder built into the side, allowing the smoker to rest their pipe on the hat while not in use.

While smoking hats are no longer widely used due to the decline in smoking and health concerns associated with tobacco use, they can still be found as vintage clothing and historical artifacts.
