Thank you for viewing. I purchased this to go mountain climbing with my child, but after using it once or twice, I haven't been able to go due to work. I had it stored in the closet, but I've decided to declutter it due to moving. It's used, but I think it's relatively clean. Here's the description: A child carrier that exhibits excellent rigidity and stability. The 24-liter storage space is convenient for storing changes of clothes and diapers. The shoulder harness, hip belt, and back system can be adjusted quickly and easily, allowing for comfortable carrying without hassle even if the person carrying it changes during the activity. It employs a back structure called AirSpeed suspension, which covers the upper back to the lower back with a lightweight mesh panel. The seamless structure conforms to the body, providing a natural fit and breathability when carried. The child seat is safe with a frame and padding, allowing you to carry your child with confidence even outdoors. The soft-touch fabric, adjustable features to fit the child's physique, and breathable side mesh panels maintain the child's comfort. The drool pad is removable and washable. The child safety harness, seat, and foot straps can be adjusted to fit the child's body shape. The built-in sunshade, which is standard equipment, protects the child from strong sunlight with UPF50. It is built into a dedicated zippered pocket and can be deployed and stored quickly. It can be easily folded and stored, making it compact when moving, and using the separately sold Poco carry case makes it even easier to carry. It's in very good condition, but please refrain from purchasing if you are sensitive to used items.
