Sun Barrier 100 Linen Thermo Hat. Worn three times. I am selling it because I haven't used it much. Retail price: 12,100 yen (tax included). This is a completely light-blocking hat that cuts 100% of ultraviolet rays, 100% of infrared rays, and 100% of visible light. The outer side is made of linen (flax) material finished with thermo yarn that is resistant to deformation, and the inner side is made of completely light-blocking fabric. This achieves a cool design while maintaining complete light blocking. It is useful not only for light blocking but also as an item when you want to create a seasonal coordination. If you are concerned about stuffiness of the head, you can remove the inner part of the head for comfortable use. Please refrain from purchasing if you are sensitive to details.
