Our two year old daughter loves this pack to the point that she often demands it before going to bed at night. You'd think it would be hard to sleep with it on, but whatever works for her, works for us.

The water reservoir is tiny, which for a two year old is fine (they are pretty much novelty drinking anyway), but it might be too small for older kids.

Probably the biggest drawback of this pack is that it lacks a sternum strap, which makes it fall off too easily.

I bought this pack for my 5 year old son, he loves it. It makes him feel just like Dad. He's worn it on short hikes and for skiing and it has worked flawlessly alway. Definately recommend it.

This is a great pack - bought on for my son (5) and daughter (2). They loved being able to carry their own water. 2 knocks on the product - 1) wish it came with a strap that went across the chest, because this tended to fall of their shoulders, and 2) needs a storage compartment / pocket for little snack.

Took it to Arches National Park in Utah. It was hot and we hiked a lot. My daughter loved wearing it and being able to have a drink whenever she wanted it. She is 4. 2 1/2 year old son had one too. He was a little less enthusiastic about wearing it, however he did and he liked drinking from it too. Worked great for keeping kids hydrated.

I bought this for my 7 and 9 year old sons. They LOVE it, but it doesn't hold much water. The tag states that this Camelbak's capacity is 35 oz. or 1 L, but it seems smaller than that. It states that this Camelbak weighs 2.9 lbs. filled and measures 12" X 7" X 1". I wish I had been aware of the measurements and capacity before I purchased this pack, because I would have purchased a larger Camelbak instead. The tag states that this pack is for ages 5 and up, but I feel that kids who are 7 and up need a hydration system with a larger capacity. This Camelback is probably perfect for kids 6 and under.

Another great product from Camelbak. However, do not buy it for a 7 year old. It is too small.
