The Koby is the most durable and dependable pack we've purchased for our kids over the years! As an owner of other Osprey backpacking packs, I knew this will probably be the last backpack I'd be purchasing for many years until my 4 year old needs another Osprey pack when he grows up. The pack features are well designed and thought out...I especially love the gear loops and the mesh pocket on the back...its great for stuffing a jacket / Kindle / or some Matchbox Cars in...for quick retrieval later. The interior of the pack has ample storage with a sleeve to keep things organized, and a smaller zip pocket (above the outer mesh pocket) where we keep quick access items as well...meds / snack / you name it. Another thing I love about this pack is that the straps are beathable and long enough to where I can sling it over a shoulder if we're out and about. All in all...it's a rad pack for kids...for hikes...school...or as a simple go-bag in lieu of a toddler bag!
I got this for my son for school because I love Osprey and it seemed the best fit for a school bag. He's 8 and it's a great size for him to wear, but it barely fits a regular sized notebook lengthwise. You have to finagle it instead of just easily slipping it in, otherwise things get bent.
