I bought this bag for work to take all my medical supplies in . this is roomy on the inside good sized pockets, light and easy to carry although I do wish it came with a longer shoulder strap. this bag is very helpful the only thing I don't get is why there is such a difference in price with each color the bags are the same just colored different. I like that i can fit my med supplies, my wallet , my books, change of clothes, water bottle and coffee cup, keys , multiple small items, this is a nice bag.
