I like this backpack a lot and so far I am using it every day, I'm 5'3" and I have several backpacks that are too big for my body frame, or way too heavy once I have stuff inside. The Pacsafe mini backpack is a great way to keep my personal "stuff" safe, and I don't have a weight issue wearing it. While I really like being able to lock the zipper up, I find it a little difficult to pull them apart, but no big deal. The reason I gave it 4 stars is because it doesn't have a water bottle pocket outside and the bottle takes space inside the backpack. I missed that part of the design when I decided to purchase it...still is my favorite pack for every day and for future travels.
