This is a must have for all flight crews. My husband uses this every time he gets in the cockpit.
It reduces the UVR and heat. There are 2 see-through and 2 dark shades. They come in a small pouch and fold easily.
He really like this product. See it in our affiliate link.
If you fly, you need this!
