Review on 🧢 Adaptable Sweatband for Hats & Caps - Ideal for Cycling, Fishing, and Boys' Accessories by Bobby Plymell

Although billed as a sun visor I don't actually use it outside but in a work environment to block out (what I believe) annoying overhead light that used to be a nuisance during the day. Once this was fixed with simple tightening, all I had to do was adjust the fit a few times to get it right and then leave it at that. Now it is comfortable to wear. So I recommend these for both indoor and outdoor use.
