Query: uncomfortable, flimsy but very roomy

The only plus of the Kipling backpack is just how much stuff it can hold. I have taken a full shopping bag of goods and fit it inside the expandable backpack to the amazement of friends. Only problem is the zippers aren't of the best quality and jam frequently and aren't made to bear the stress of the amount of goods that can fit in this backpack. The overall design is mediocre at best and the straps are pretty uncomfortable when you're carrying anything of substance. Backpacks like the Kensington Contour have super comfortable form fitting straps but hold next to nothing aside from your laptop. If you need sheer volume, buy the Kipling but don't be surprised if you need to have the zipper fixed in a year. It is the biggest small backpack I have found and that's what I need most. I just wish it wasn't so damn uncomfortable.
