moodytiger | Ultra-Light Load-Lifting Spine-Protecting Waterproof School Backpack

It's quite lightweight. No unpleasant smell. It's also very stain-resistant.

The moodytiger backpack has solid and exquisite craftsmanship, and it's so lightweight that it really takes the pressure off a child's shoulders. The ergonomic back panel fits the body perfectly, and the waterproof fabric is great for resisting rain and dirt. The internal compartments are spacious and keep things organized. The color is very cool, my kid loves it! The straps are soft and don't dig in, and the size is just right for my child who is 145cm tall.
