In this photo provided by Kaiser Health News college students Colin Berg, left, Connor Dreher and Brady Bowman stroll through downtown Boulder, Colo. on Tuesday, Nov. 10, 2020 wearing matching neck gaiters. Some research suggests the thin material used in gaiters does not block as much of the coronavirus as cloth face masks do, even when worn correctly, doubled over and covering the nose and mouth.
