fishwrote a review of Columbia Freezer Zero Bandana on August 12, 2016
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
As long as the bandana was single or double layer it stayed cool. But only as long as it was wet. On the high windy plains of Wyoming it dried out in about an hour or so. More than double layer around the neck provided little or no comfort from the heat.
