Beanies aren't just a way of keeping your head warm in the winter -- these skull-hugging cloth caps have also become fashion statements for both girls and guys.

Recently, we've seen tons of celebrities sporting beanies, including some super swoon-worthy male singers, like Justin Bieber, Austin Mahone, Cody Simpson, as well as One Direction members Niall Horan, Harry Styles and Louis Tomlinson. Even in the Cali heat, these dudes like to bust out their beanies. It helps conceal a bad hair day while simultaneously adding a little edge to an otherwise plain outfit. 

Check out all of these guys wearing beanies in the picture above. Who do you think looks best? Is it Justin Bieber, who rocks ribbed caps while visting chillier climates, or perhaps Austin Mahone, who sometimes slips on a beanie prior to performances? BUT, Cody Simpson does look pretty dang dreamy in that beanie, with his blond hair poking out the front.

Then there's the One Direction guys, who all look super cute in their beanies. Niall loves his gray beanie, and we've seen Harry sporting that olive green one before, as well. Finally, Louis keeps his hair in check and his ears toasty with his charcoal skull cap.

Which guy do you think looks best in their beanie? Vote below!
