What’s the difference between Baby Carrier One and One Air?
These baby carriers share the same features but are made from different materials. Baby Carrier One Air is crafted in an airy 3D mesh, and Baby Carrier One is made from a soft cotton blend. Both materials are soft and flexible, but the cool 3D mesh is a better choice if you easily get hot or live in a warm climate.
