This product comes in two sizes, but the sizing chart is inaccurate. I bought this hat as a Christmas present for my Fiancee (in XXL) because we are going away this winter. I typically have a woman's large head, and this hat doesn't even fit me. I had to have him try it on for five seconds and he already had a circle around his forehead and a headache. We are unfortunately going to have to return it because the XXL sizing is actually a large fit at most. And they're going to charge me shipping to return their mistake. What a scam.
