Source love kids to spend their time outdoors, so Source have 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. The great look and comfort is tested not to interfere with movement. And your kids are good to go!
