I travel exclusively with Backpacks now...and I've tried them all. I've found the layout, durability and weight of the bag are all top requirements.
For 5 days of 1 bag travel, I would not recommend this bag.
1. It gives up way too much size and it quite a bit smaller than the allowable size for carry on.
2. I don't know the weight, but it doesn't look light with leather.
3. Make sure the zippers are YKK. The only zippers I trust.
