The main body fabric is made of a highly durable PU coated material, but peeling may occur due to strong friction or deterioration due to usage conditions. If you leave it wet for a long time, it may cause discoloration or deterioration, so please be sure to dry it before storing it. Also, please note that if placed in high humidity conditions, the fabric may wrinkle. Please note that it is not completely waterproof and cannot prevent water from entering through the zipper or needle holes in the sewn parts.
