If I've missed something already on this, I apologize -- couldn't find it in a search... I try to still walk outdoors regularly because I live in a small apt. and of course am not going to go to the gym. Masks, as you all know, are tough to wear and especially for me in hot weather (Texas). Have seen ads for cooling neck gaiters which look like they'd have some opening at the bottom for easier breathing. They are I think only 1 fabric layer thick, though, and I don't know how they fit. Does anyone have experience with this option?
