There are a lot of things to look for before buying an earflap hat. Consider the following to settle on the best.
Earflap length: Depending on where you live, you'll choose different lengths of the earflap. For instance, a person living in extremely cold places will choose Trapper Hat Aviator Earflap Hat over the Fancet Womens Earflap cap because it has longer flaps that will cover ears to the chin while the latter only covers the ears.
Material thickness: Other than looking good the reason people buy earflap hats is to protect themselves from cold. The thicker the build, the better it is against the winter cold. Ensure your choice has a fleece lining and uses fur within for coziness.
Waterproof/Windproof: If it is going to be snowy and you will probably get in contact with water, it is better to get a waterproof hat. Look for windproof features like the bill and a mask as well, if you are going for speed sports during winter.
Wearability in warm places: What if you wear your hat and realize that the weather is warmer than you expected? A good hat will allow you to fold the ear flaps without struggling then later free them down when it gets cold.
Color and Design: Women have preferences in hats that vary from those of men. While a woman might go for bright colors with design drawings on the hat, a man could choose one in a dull color and fewer drawings. But you should not be limited by the fashion stereotypes set by others. Look for what pleases you.
