I have nice experience with the bag from last 3 years and still using that bag in regular usage.
I bought this bag for carrying only my books and some personal stuff.
but I used that bag in every condition from tough to ruff.
at the time I bought that bag I have zero knowledge about its carrying capacity but from my personal experience I has carried up to 5 to 6 kg.
so, the lather and the styles and design is vary convenient, good user friendly and stylist for youth.
so, as per my experience you can understand that the value for money is excellent.
