However, if you purchase multiple items or if I can combine shipping, I may be able to offer a discount on the shipping cost. Shipping will be via Yu-Packet Post. The hat will be folded in half. There shouldn't be any creases, but please take it out of the bag immediately upon arrival. "UltraViolet Protection Factor" is abbreviated as UPF, and in Japanese, it's called "UV Protection Index." While SPF and PA are listed on sunscreen, UPF is displayed on clothing, indicating how much the garment protects against UV rays. The ratings are divided into three categories: "15-24," "25-39," and "40-50+," with higher numbers indicating greater UV protection. UPF50 means that the clothing cuts UV rays to 1/50th, meaning it blocks 98% of UV rays.
