○ Resurrection Rain Bucket Hat (WHITE) RR2-3HAT03 UNISEX Men's & Women's M Size Head circumference 55-57cm, adjustable with Velcro ○ Water pressure resistance: 8,000mm Moisture permeability: 8,000g/m²/24h level Regarding "water pressure resistance," it indicates how much force the fabric can withstand before water penetrates it. The higher this number, the better it prevents rain from entering. The 8,000mm rating means that even if an 8-meter (8,000mm) water column is placed on a 1 square centimeter of the fabric, water will not soak through, providing sufficient functionality for a rain hat. Next, "moisture permeability" is important for both rainy and sunny days. This indicates how many grams of moisture are released to the outside in 24 hours. As a standard for moisture permeability, it is generally considered that if it is 5,000g/m²/24h or more, it is less likely to get stuffy. With 8,000g/m²/24h, even though it's a rain hat, it seems unlikely that the inside of the hat will get completely soaked on a sunny day.
