The Buff is perfect for running in all types of weather! One of my favorite features about the Buff is that it wicks sweat away from my forehead, keeping the sweat out of my eyes during the warmer months. Even better, the Buff keeps my ears warms during the cooler months. Another great feature about the Buff is that it keeps my hair back when I need it to and even acts as a skull cap to cover my whole head. I first used my Buff last February during my first half marathon. My unruly hair needed some taming and it was a chilly morning. Thankfully, my Buff kept my crazy hair back for all 13.1 miles of the race, all the while keeping my forehead dry. I would highly recommend a Buff to anyone!
