We have been using skybag travel bags during our domestic travels since more than 2 years. I really would like to praise the material, spinners, size, storage and the decent looks of the bags.
The material is long lasting and also it gives 18 months of warrenty.
Coming to bagpacks, I would say it is multipurposebag ike it can be used for official purpose as well as for college students. It has very good storage capacity with many small pouches. You can carry it during the tracking as well as for small tours.
