Didymos Baby Wrap Slings

Hello, Rabbis.

Would the baby wrap sling which is worn by the mother be permitted for wearing a baby on shabbat in a city without an eruv?

Thank you very much!

No.
In essence it’s a “method” to enable carrying not a question of an article of clothing and therefore forbidden.
