Baby Carrier OMNI360 Cool Air Khaki Green There are no noticeable stains. I think it hasn't been used much. Please check the photos and only purchase if you are satisfied. Everything in the photos is included. The Omni 360, which allows forward-facing carrying, now comes in a cool air type with excellent breathability! The omni360 can be used from newborns without the need for an optional newborn insert. Once the baby's neck is stable (around 5 months old), you can carry the baby facing forward.
