This is a nap mat bag purchased from HugMug. It's the type with a rain cover. Material: 100% nylon Color: Brown It's water-repellent, so it's safe even on rainy days. There's some wear and tear, but I think it can still be used. I also think the water-repellent function still works well. It's easy to store and can be compactly folded when not in use. Simple is the cutest.
