Very thin material which makes it perfect for the summer. I love to wet it and then wear it when it’s really hot. Great quality.

Great running hat.

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.
