Under Armour visor clips, worn by Saquon Barkley, are quick-release clips that allow you to put on and remove a visor with ease. They simply screw on and off (no tool required), and are optimal for taking your visor off quickly due to bad weather, fog, etc.
Saquon’s are grey to match the Giants facemask and you can get them in red for $10 at DicksSportingGoods.com.
