    Great running hat.
    Size: One Size, Color: (001) Black / Black / Reflective
    I absolutely love this hat, it is so cute and great for warm weather. I especially love to run with it, you can tighten it easily so it does not blow off if it is windy.

    Perfect for running, I love this hat.
    Size: One Size, Color: (025) Castlerock / Castlerock / Reflective
    This hat is perfect for running in, it's very light weight and breathable so it doesn't get annoying or hot when you're running in the sun. It's easy to clean, just a quick hand wash in the sink and it's dry in 30 minutes. I have a very big head and it's fits me great. If you have a very small head it might be a bit big.
