You can waterproof your backpack as soon as you receive it, and the vegan tech material can be well maintained with leather care products to keep it supple for many years.
Please make sure that the waterproofing spray you purchase is suitable for TEX materials and follow the recommended distance during application.
Note: The warranty does not cover any damage caused by impregnation! It is therefore best to test the spray beforehand on a less visible area of the product.
Stubborn stains on the vegan tech material can best be removed with a bit of lukewarm water and mild soap, or with a cleaning eraser, which you can find, for example, at a drugstore. Stains on the fabric can also be effectively cleaned with a mild shampoo.
Be careful not to machine wash your backpack or use chemical products.
