So, I purchased this bag around two years ago, and I have used it everywhere, from school, to overnight trips, to camping, to traveling across the world! This, I have got to say, is the all-around bag for anyone. Mainly, I use it for carrying around my school binders and books, of which I have a great amount, as well as my laptop, but the bag holds firm. I remember when I was thinking of purchasing this, I was reluctant due to there not being an exchange policy, but trust me, you won't need it. The resiliency of this thing is amazing. Two rough years going, and this bag is still in almost-pristine condition. I've walked through a monsoon with this thing, and everything inside stayed perfectly dry. I cannot stress how pleased I am with this product, and how pleased I am with Manhattan Portage for creating such a fine product. (This is the only thing I have of them, though.) Whenever this bag breaks (Probably in a few hundred years. Legit.) I will immediately buy another one of these bags. I might, however, try another series, or get the larger one, but I'm definitely getting another one from here, as I know I won't be disappointed. (Far from it.) Manhattan Portage, please continue making products of this quality. Decades from now, I expect to be walking around with one of your bags.
