I have used car back twice once in my school time and the second time is my college life the quality of material is not good they are made up of very poor fabric due to which they get easily torned. Steps have a good question so they are comfortable on shoulders but the quality of zip is not good.
The biggest problem is that they are not waterproof in budget range I am using a sky bag of 1300 which is not a waterproof bag whether they have a laptop cabin so these kind of things are not acceptable because other brands like Wildcraft an American Tourister offer waterproof back in just 800 or 900.
Due to which they lack value for money deal.
