This bag is nice and has a lot of space, compared to the Swiss Gear bag I have.
I had bought this for my husband since he travels a lot and likes to keep a spare backpack with all his travel accessories ready. But after checking out the bag, he actually made this is permanent bag keeping the swiss gear aside.
He has been using this bag daily for more than a year now and its lasted well. The zippers are good and smooth.. All the small pockets here and there are useful.
The cloth is a little cheap compared to swiss gear, but thats what makes it roomier. I have actually managed to keep our 2 day picnic stuff in it without cramping too much.
It even has a yellow rain shield which comes in handy whenever it rains and you have to walk out of your office till your car parking.

On the downside.. the bag has its own weight, would have preferred something lighter, but I guess thats how it is with most of the backpacks.
