Purchased Jansport Scout Backpacks for my 11 year old sons. The primary feature is the external frame that adjusts easily as they grow. The frame's bars provide perfect placement to strap on bulky items like sleeping backs, pads, and tents. This model allows the boys easy access to the pack's main compartment through the front panel. Likewise, easy access to the lower compartment. The front stash pocket stores items for easy access without opening the main compartment. Four additional storage compartments on either side of the pack allows them to tote items like 1-quart Nalgene bottles, rain ponchos, and mountain paper.
