Size: F 56-59cm I bought this but rarely used it, and it has been stored at home. This is a deep-fitting casquette, so you don't have to worry about going out bare-faced for a quick walk or shopping trip. The underside of the brim uses 100% blackout fabric. The blackout rate does not decrease even if it gets dirty or is rubbed, and the blackout performance is maintained unless the fabric tears. The fabric on the crown and around the head achieves a UV (A wave/B wave) shielding rate of 99%, shutting out ultraviolet rays! In addition, the black fabric on the underside of the brim protects your skin and eyes from reflected light from the ground and walls. An inner size adjustment tape is attached, making it possible to change the fit depending on the situation. Also, to reduce the heat as much as possible, the lining uses contact-cooling fabric with antibacterial and antimicrobial treatment, providing a cool and smooth feel. Regarding shipping, we will fold it to reduce the thickness and use only simple packaging. Thank you for your understanding.
