The perfect bag for traveling

I just took this bag out for the first time to a 2 week trip through Brazil and the bag was even better than expected. I bought the medium-sized bag and was able to fit more than I could possibly ever need out and about on the streets. The bag is well-constructed and heavy-duty and shows no use whatsoever after using it for 12+ hours everyday for 2 weeks. The weight distribution works really well and my back never tired even with carry a lot of weight in the bag. If you are looking at buying a bag, I would seriously check out each size, because the medium was even bigger than I anticipated. This bag would be great for any traveler or person on the go.
