This pack has grownup features that fits younger explorers: room for 1.5 liters of water, a bike tool organizer pocket, and zippered essentials pockets. CamelBak have also added reflective strips and a safety whistle to make kids easy to spot on the trail.
Your kids will love carrying their own water and snacks. You might find they want to stop more often to make the most of their new pack and access to their own snacks.
