Designed for ages ten through 18, the Gregory Kids' 4272cu in Wander 70 Backpack is perfect for week long and longer trips. the VersaFit suspension system allows it to adjust across a wide range of small frame users, while the Wishbone Wire internal frame helps lighten the load through equal weight distribution and an adjustable torso length, which eliminates the need to constantly re buy new packs with every season. The over sized U zipper main compartment access makes it a breeze to pack and unpack your gear, while the top loading design with cinch closure and compression lid keeps your situation tightly together when you head out onto the trail. Never be without water thanks to the internal hydration sleeve with a hose guide, as well as the dual water bottle pockets on the sides of the pack. External gear loops safely carry random items that won't fit in the pack, and a trekking pole attachment lets you bring along a fishing rod or hiking pole for your adventure.
