I'm a petite adult female (5'2") and I wanted a small backpack that had narrow enough shoulder straps for my frame, and a good waiststrap -- that I could afford. This fit the bill. i love it! Fits me better than any backpack I've had, my 12" laptop fits perfectly and feels light as ever. The clips and material is cheaper than the more expensive (adult) Osprey bags, but it's not as though it's about to break... and it's $20 cheaper than the cheapest of their adult bags, so that makes sense. There's a little whistle on the chest-strap that works and makes me feel safe at night marching around a city.
Also, great for bike riding.
Overall: Highly recommend!!
