Cute and comfortable, though a little big without tightening a bit
Size: One Size, Color: (100) White / White / Reflective
Love the bright color and material. It fits a little big at first but has the ability to tighten quite a bit so it should be fine like it is for me. I just have a smaller head. It has great coverage. Feels comfortable as well.

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.
