My larger 4.75yo son needed a new backpack for his outdoor classes and camps coming up. He was using his 7L mini Fjallraven, which has been great for preschool for the past few years, enough for a little lunch and a water bottle. But it wasn't large enough for his winter outdoor class. The Jet 12 can carry a lunch, another layer of clothes in the big pocket, plus little pockets for sunblock, sunglasses, magnifying glass, gloves, etc. We something to fill the hydration sleeve, which frees up space for everything else. The fit is perfect and highly adjustable, he's about 3'4" and 42lbs. We've only had it a short time, so I can't say anything about wear over time, but he wore it all day yesterday and it moved with him easily, something that will make his outdoor class and camps that much easier. What a great product. I'm not looking into an Osprey as a school bag for kindergarten later this year.

Our family loves to take day hikes and we noticed that my husband was always stuck carrying his pack with the kid's water bottles, sweatshirts and food. After climbing Blue mountain in the Adirondacks we decided that our 6 year old needed her own pack. After a lot of research, we decided on the Osprey Jet 12 for her. We purchased a 2 liter camelback to go with it. She loves her pack and I love that she is drinking and staying hydrated on our hikes. It is big enough for an extra layer, a snack and a few Barbie dolls that sometimes come along. I expect she will be able to use it for many years to come and be able to pass it down to her younger brother.
