As I had this bag for 2 months I can say that his bag is pretty good and one of the best priced sling bag I could find that fit my needs! As a student this bag has been a lot lighter on my shoulders and back, it's a godsend. Not saying you can carry 15 pounds of stuff in there and be fine but maybe a text book, a light laptop, and a notebook is enough without causing too much back pain.Running with the bag is a bit awkward to though. As you run, the bag might slowly move towards your side. I don't know whether this is just a sling bag issue or not but just something to watch out for. But,Compared to other bags of the similar category, this bag has been the best starting from it's form factor to allow larger sizes laptops to fit to being somewhat water resistant!Pros:- Large Bag that's able to fit a 14 inch laptop- Somewhat(???) Water resistant as heavy rain hasn't affected the contents within the bagThe bag is lined with a fabric inside so whenever it rains usually the outer material soaks it up to prevent leaking onto your stuff. Compared to other bags I got previously, This one did it's best to not leak- multiple compartments and pocketsWith 6 pockets (including the main one) this bag allows you to store a lot within it. Personally for me, I use many of them to carry utilities when I'm out and about- Decent price for size- Durable material and cool designCons:- Quality.The quality of this bag is not the best. You get what you paid for but there's room for improvement on the manufacturing end.When I received my bag, One of the o-rings were slightly ripped from the fabric and the pouch button came looking slightly dirty. YMMV if you get a bag, it might be perfect, or there could be some slight to major issues.- Large StrapNot only is the bag is large, but so is the strap carrying it. In order to get the bag to fit me nicely I had to pull the strap all the way out. If I was a bit bigger/taller, perhaps this would be an issue though. Another thing to look out for is the actual strap. When I was done fitting it, I was left with 8 inches of a 1.8 inch wide strap loose around. I needed a pretty big clip in order to keep it all nice and tidy.- Small Water bottle PocketThe water bottle Pocket is a little too big for a normal plastic bottle, but too small for one of those medium sized jugs/tumblersAll in all, I would say this is a good backpack to buy if you're looking for something large and it's great for me as a student. Thank you.
