Over the years we worked with many engineers and designers to create the product imagined that one sunny afternoon. The best part of Flip'N Shades is they can attach to any visor and work whether or not you wear prescription glasses. They are infinitely adjustable for a perfect fit anytime. When the sun goes down, you just flip them up out of the way into the storage position. This means that your shades won't get lost in your pocket, a kitchen drawer or your cars glove box anymore. Flip'N Shades has an ANSI rating for commercial use and they come in a variety of colors. In developing the product, we were told to go to China where it would be less expensive to produce them. But Flip'N Shades are designed and made right here in the USA. We have even partnered with a US cap company so you can take pride in the fact that all our products are 100% American made and assembled
