I use this for running and biking to work. Stays in place without much bouncing. Storage is tight but sufficient for a set of clothes (pants, button up shirt, etc) plus wallet keys and phone.
Good backpack. We found the bottom zipper compartment so all is well. The straps are great as they curve inward and allow full arm movement on a bicycle. We will be purchasing a couple more of these backpacks.
I just got this from the mail, and it’s amazing! Good for biking, day hike, and other outdoor activities. Definitely recommend this.
