Sky bags is quite a popular company which manufactures back packs, and suitcases.
I like it for suitcases only as they come in funky colors.
What I do not like is the material they use in making back packs. I ordered a skybag bratt model from flipkart 2 months ago for rs 1200/- and after one month the upper part of the bag got torn with some days of travelling in the rush of delhi metro. I was very disappointed with the durability of the bag.
The material was quite thin in the bag which I did not know before buying but whenever I see a skybag I see the same kinda material which gives me a feeling of avoiding it. Till the material is changed.
