REI offers the Buff Women's Original Buff in Groove, Wiluna Graphite, or Wod for $9.83. Opt for in-store pickup to avoid the $5.99 shipping charge. That's $6 under our winter mention of a shipped unit and the lowest price we've seen. (It's a current low by $4 in any style.) It can be used as a bandana, hair band, scarf, neck gaiter, or sun guard.
