For anyone who doesn't know...here are a couple of Buff examples (from the same weekend...I swear I don't always wear the same jersey! ) The Buff is the thing around my neck in the first photo, and on my head under my helmet in the second one. If it's cold, I wear it covering more of my head and pulled down over my ears. It's very light weight, wicks moisture, dries quickly, and is stretchy.
