A new Baby Carrier One will be released in the US and Canada in 2019. All other versions of the One are still safe and great to keep using. We made a few updates to make your baby wearing experience even more comfortable.
Those updates include:
New 3D mesh on Air carriers
New shoulder padding for parents to help distribute child's weight more evenly
Higher head support giving newborns more protection
Wider maximum seat area
Redesigned buckle to adjust head support and help keep the flap folded down when baby is outward facing
Thinner padding and less fabric to make a more environmentally-friendly baby carrier
