This backpack uses water-repellent fabric. Even when water is poured on it, it doesn't soak in but beads up and rolls off the surface, so you can rest assured even in sudden rain. • Stain-resistant for easy cleaning! Not only water, but also mud and other stains are less likely to stick, making cleaning easy. Even if it gets dirty, the dirt can be removed by simply rinsing it with water or wiping it lightly. It's perfect for outdoor activities and protection from mud splashes on rainy days.
