Excellent bag.
Waterproof, holds a lot, has enough compartments to separate one's belongings.
I have had it for 2 years now and with basic care and attention to the leather, it looks like it was bought yesterday.
Buy it fearlessly. It is not cheap, however, if it lasts as it appears, it ends up being extremely cost-effective in the long run.
Not to mention that you can have it with you in a multitude of occasions without ever looking either excessive or lacking.
