An updated version of the original version. The Emi V2 features a removable backpack. With the Emi V2, you can enjoy the conveinence of a backpack when you need it. This design is not only convenient, but the backpack acts as ballast, with equal weight distribution on front and back.

Whatever way you choose, the baby rides comfortably in front and padded shoulder straps always keep you comfortable. Translation: The Emi V2 is comfortable and convenient when you need it.
