I like it, too, and Fossil leather is always lovely. My only concern is the length of the strap when you use it. Do you have a bag you could measure to compare where this one would hang on you? The picture makes it look a little long, at least to me. If it is, then I don't know how comfortable it would be for you. Otherwise, I think it is a great bag.
One thing I would do is figure the measure of space you think you will need. Are you taking a laptop, for instance? If not, your options for shape are wide open.
I have always had good luck with the ebags site when I needed something in particular. They have sales pretty often, too. Their site was where I first found my all-time favorite brand for everything: Ameribags.
Finally, you may want to consider whether you want to spend a lot on a bag this large if that is not your usual preference. You can find lots of nice ones in materials other than leather, and you could still treat yourself to a really nice, smaller leather one. You might even want to take both on your trips.
In the meantime, I wouldn't put much stock in what that Fashion Board says. The few times I have looked on there, I thought their suggestions were both wild and wildly expensive.
If you find something that you
really like, then it will be the right bag to get.
