Better than most adult packs, the Ace 38 Backpack makes your weekend backpack look like a potato sack. Its AirScape suspension system adjusts in length to accommodate your kid's ever-growing body, and it stabilizes the pack's gear, transfers weight close to the body, and ensures superior breathability for comfort. The Fit-on-the-Fly waist belt acommodates different hip sizes so every child in your family can use it.
