I've always had trouble finding hats that fit me and also look good at the same time. I have an average size head, but a lot of hats are too deep for me. I decided to give notch hats a try, but figured out I didn't actually need the notches with my current sunglasses. I loved the hats so much that exchanged for the notchless versions. Let me just say that this company's customer service is OUTSTANDING!!! They have gone above and beyond to make sure I find the perfect fit. I plan on adding more hats to my collection soon. Highly recommend this company and their amazing hats!
