Lululemon Fast and Free Ponytail Running Hat ($38)
Turn this Lululemon running hat around and check out the big opening in the back, which is wide enough to incorporate ponytails of any height. Get it in four colors, including white, black, storm teal, and sonic pink. But no matter which you choose, you'll get reflective detailing, an interior mesh sweatband to catch any drips, quick-drying fabric, and an adjustable back closure for a custom fit.
Why we love it: Reviewers are obsessed with the ponytail hole. "I have a ton of hair and have troubles fitting my ponytail or bun through the hole that normal ponytail hats have. This hat is perfect for my average head size with the adjustable band and allows all my hair to be in a comfortable high pony or bun for my runs. It doesn't slip up or blow off when it's windy and doesn't leave a big dent in my forehead like other hats do when I get them tight enough to not blow away."
What's worth noting: Some customers report the hat being too big and say that the adjustable strap doesn't go far enough to fit their head. Because of this, one reviewer said the hat "rides up constantly and slips up my head."
