The Ergobaby Alta baby carrier uses breathable mesh material. It's easy to put on, just fasten the buckles. The back panel can be removed for use as a hip seat alone. This hip seat is perfect for "short carries" when your child starts walking and you need to put them down and pick them up frequently. Purchased new on Amazon in July 2025. (Original price: ¥28,490) I bought this as a secondary carrier because it can also be used as a hip seat. I tried it at home 3-4 times, but both my child and I are small, so it felt a bit too big, and I stopped using it for a while. Later, I received another baby carrier from a friend, so I'm selling this one. It's almost unused, so it's in beautiful condition. - Brand: Ergobaby - Model Name: Alta - Color: Natural Beige - Accessories: Instruction manual - Design Features: Mesh material - Size: Free size Thank you for looking.
