Perfect fit
Size: One Size, Color: (001) Black / Black / Reflective
I ordered this to wear during my upcoming vacation. It will shade my face from direct sunlight. I initially wished the brim was just a tad bit shorter but then I realize the current brim size will serve the purpose; that being the reason why it was purchased.

Perfect Visor
Size: One Size, Color: (001) Black / Black / Reflective
I bought this thinking I wouldn’t like it. I was so wrong. This is lightweight and the perfect fit. What a great value. It’s so comfortable on your head and the vent on it was a great idea. Adjusts easily and just a great buy.
