The Four Position 360 Performance Cool Air Baby Carrier is the newest addition to the Ergobaby award winning collection. The breathable 3D Air Mesh lining keeps baby cool all-year round while its unique, structured bucket seat, padded shoulder straps and wide supportive waistband offer exceptional comfort and ergonomics in all carry positions. It provides four comfortable and ergonomic ways to carry your baby: on your front facing either you or the world, on your hip and on your back. You will benefit from the easy-to-adjust padded waistbelt which features lumbar support and curved padded shoulder straps for maximum comfort. It is suitable to use from birth with the newborn insert (sold separately) or from 5.5kg without the insert. Cosy and protected, your baby will be perfectly cradled and cushioned. Please note: The references to ages and weights are only general guidelines and each baby's development is different. The Easy Snug infant insert should be used until your baby demonstrates strong head and neck control and can be seated comfortably in an ergonomic, M-shaped position within the Carrier, even if their weight is more than 12lbs.
