It's fun, it looks good and it's functional: The SPRY Hydration Pack for Kids - small to medium size - has a separate compartment for the 1.5L Widepac Hydration System (included), two zippered pockets for snacks and other essentials, and external cargo space for a jacket. 

1.5L / 50oz Widepac Hydration - Cargo Space for Essentials

We love kids to spend their time outdoors, so we made a pack just for them. The 1.5L Widepac is stored in a separate compartment not to interfere with the cargo. There are two zippered pockets for carrying snacks and essentials and an external cargo space for carrying a jacket. The mesh shoulder straps and back make sure there's plenty of ventilation.

The pack is designed to comfortably fit small to medium size (for kids size medium to large check out our Spinner NC for Kids). The great look and comfort is tested not to interfere with movement. And your kids are good to go!
