I have two members of skybag with me, one is a laptop bag and other one is a rucksack. I bought the laptop bag a year ago and rucksack 4 months before. Starting with laptop bag, the material is of great strength and quality is superb.
It has enough compartment for your accesories and perfect pocket to design to keep the laptop of almost any size. The straps are thick and feel strong. I am using it from past one year without any complain. Under its impression I bought skybag rucksack, though costly but its worth for the service it gives. The fabric material of rucksack is outstanding. Enough number of pockets at bottom, top and side. A very sturdy belt and strong straps. Its 47L rucksack and you can easily carry a bagful weight on it, without any fear of tear.
I must admit that bags are somewhat costly, I got laptop bag for Rs. 1700 and Rucksac for Rs.3500, but if you consider their quality and think about long term use, they are worth to buy.
