I want one sooo badly but after trying it a few times in store I know it's too heavy for me while being a commuter city girl who has to take trains & busses to work. If I still lived in Florida and could put the bag in my car etc, I would get it.
The weight really does depend on what you carry. One potentially rainy days, just adding my compact umbrella seems to add a ton. If you were to just hold empty Antigonas, you will likely find them no heavier than most other bags.
