At first glance this looks like an ordinary backpack. First thing I noticed is that there are so many pockets/compartments on this backpack. On the front, it's got a small lined pocket for delicate items like glasses/sunglasses, a large front pouch with vents to fit sneakers (fits my size 13 running shoes) and right above is another small zippered pocket (perfect for easy to grab items). The main compartment is nice and roomy and there's also a mesh sleeve with a zipper. Behind it is a more slimmer compartment where you can slide a laptop/books into and it also has pockets for stationary. On the outside, there are side pocket for water bottles, two upper side straps for additional accessories. My most favorite part is that the backside has a strap that can slide over a suitcase handle! Super useful for the airport. I'm 6'1", and this backpack is a perfect size for me and I love all of its features. However, I do wish there was a little more padding for the laptop compartment, but I think it should be sufficient. Overall, this backpack is perfect for gym trips, as a carry on at the airport or just regular use.
