Typical Mid March Start on the AT in 2018. Already have a 1.05oz Schampa Polypro Silkweight Balaclava. Yet, I have seen so many Gear Vids and thru hike vids in which the Buff seems to be getting a lot of use. I am not sure of the difference between a neck gaiter vs. a Buff other than there are some merino MidWeight neck gators that seem to weight much more than my Balaclava. Just wondering what people think - Buff or Balaclava?
