Hello dear, our bag is made of anti splash fabric, which can only prevent a little water. If it is rained on for a long time, it will still get wet

Cleaning bag method:
If cleaning the backpack, it is recommended to wipe it with a dry and damp cloth. If cleaning some places, brush off the dust first, and do not soak it in washing powder. If it is just some dust, pat, wipe, and dry it.

If there is a stain and it is dirty, you can use a wet towel and add some laundry detergent or detergent to wipe the stain. Soaking is not recommended and cannot be machine washed.
This will make the backpack last longer.
