The Buff is our most versatile piece of headwear. A Buff is a tube of seamless, stretchy fabric that fits around the head in a variety of ways. We like the High UV Buff - it provides 95% protection from UV rays. The fabric is called CoolMax Extreme - it wicks moisture away, so that the fabric stays warm in cool weather and doesn't get too hot in the summer.
We like the SunGuard style, pulled right up over the nose, or down as a Neck Gaitor. For those with longer fly-away hair the Foulard and the Hairband are useful. The Hood is a good one to use over a cap if your hair is slippery, as it stops the cap flying away! As a Neckerchief or Wristband it is out of the way if you are not in the sun.
