Here's what others have to say...


nice but big

  • Familiarity:I've used it several times
  • Fit:Runs large

I have an average sized head and this thing runs huge on me. However, it's a great hat and is light weight and great for running, being in the sun, hiking, etc. I have this and the OR Swift cap and love them both but they have VERY different fits - This one is longer brimmed and larger in the head, but I prefer the strap on the back and like the fabric better - the OR hat has a better fit for my head, I think, but the fabric isn't as breathable and air permeable as this.
