To keep your back, shoulders, and hips from aching when you take your little one for a walk, osprey incorporated their award winning ag (anti-gravity) backpacking suspension system into the poco ag child carrier. Lightweight aluminum stays provide load stability and the mesh shoulder harness and back panel combination keeps you comfortable for the long haul. Child safety and comfort is paramount. The child cockpit is fully framed and padded and the butterfly harness is fleece-covered. When you set the pack down, the base is extra wide and has a locking foot bar for stability. Two large, reinforced grab handles ensure secure pickups. The child seat has built-in safety leg loops.
