Baseball hats are very popular accessories, but they can also have a number of problems. One common problem is that the hats can easily blow off in the wind. This can be especially troublesome if the hat blows into traffic or into water. A second common problem with baseball hats is that they can easily get dirty. This is especially true if the hat is worn outside and gets covered in dust and dirt. Finally, baseball hats can also be uncomfortable to wear for long periods of time. This is because the hats are typically made from materials that do not allow air to circulate well.
