The head circumference is approximately 54-62cm, and the size can be adjusted. This is a camouflage cap purchased from an overseas shop. It has only been tried on and has not been used, so the condition is very good. The simple camouflage pattern is easy to match with any outfit and can be used by both men and women. Please note that this item has been stored by a private individual, so it is not perfect. Shipping will be done by folding it up small and in simple packaging, so please be aware of creases. If you are concerned, please refrain from purchasing. Thank you for looking.
