Any one own the waterproof keepall 55?

I love this bag and probably gonna pick it up this weekend. I do have a few questions though:
1. Can this bag be used as a daily gym/work bag? I'm 6'2" 220 pounds.
2. Going to Paris in 2.5 weeks, should I buy in Paris or just buy in the U.S.? Will I save $$ buying in Paris?
Did I mention that I'm a male.

Thanks 4 the help
