I have a wildcraft bag . Its now one year I am using it . I use it very roughly but after one year it is in very good condition. The bag is fully water proof . I bought this bag online and it was not that much costly at all. Fabric quality is good. The colour and fabric is undamaged still after few times wash and after one year.
This is value for money bag. Wildcraft has a lot of collection of bags with different colours, different style. They have a collection of separate style for boys and separate style for girls. The zips are also very good.
I will suggest you to buy wildcraft bags. Its very good.
