Necktube.  Headband.  Face cover.  Nose holder upper.  Whatever you call the Discrete Neck Gaiter, it has a million and a half uses.  The super-soft and seamless polyester has a great feel and is still incredibly breathable.  

Perfect for fly fishing to keep your face out of the sun (and bugs) or roll it into a headband if you're hitting the trails for a run or approach to your favorite bouldering spot.
