I purchased this new but am selling it because it wasn't what I was looking for. For reference, I wear a New Era size 7 1/2 (59.6 cm). It's fully mesh, so it won't get stuffy and should be comfortable to wear at all times. Please consider this as a reference. *Please purchase only if you understand that this is a used item. *Please consider the condition based on the photos. *Shipping will be done in compact packaging. Please understand this before purchasing. *As this is stored and inspected by an amateur, I try my best, but there may be minor oversights. Please refrain from purchasing if you are sensitive to such things. *To prevent swapping and because this is a one-of-a-kind item, returns and exchanges are not accepted. *Photos are taken by an individual, so the color may differ slightly from the actual product due to lighting. *Please consider the item at the current price. Thank you.
