Review on 🧢 Mens Headband - Ultimate Sweat Band for Active Men - Ideal Head Band for Running, Yoga, Exercise, Basketball, Cycling, Football, Tennis - Boost Athletic Performance with Moisture Wicking Hairband by Josh Jeffries

I don't really know what they are for but I use them to cover my ears when the temperature is below 20 degrees F or when the wind is 20 to 40 degrees over 10mph is too tight for a good fit. Additionally, the material of this Tough Outfitters headband feels poorly breathable after activity. It seems to absorb and retain moisture. Also, the seam isn't as flat as I like, but I don't like feeling the seams against my skin, so this may not be an issue for others. I've attached a closeup of the seams and seam. The Tough Outfitters headband comes in a resealable pouch. With the same weather, I can use CoolRunner ASIN: B07K9YF6YC with better results. Due to the extra width at the front, the CoolRunner headband can be folded in half for extra thickness or used in a single layer. It also has issues that I won't get into here, but when I have two in my gear bag I prefer the CoolRunner headband.
