I recently needed it during a local fire storm. It was very windy and raining ashes. My buff kept me going!
Extremely cool design, comfortable, and, like all Uncharted products, extremely high quality.
Face cover is comfortable, even now that it is getting warmer, and stays up. Wore this around my neck hiking and kayaking and kept it from getting burnt. Also was great at keeping mosquitoes from biting my neck when hiking.
