Is this a "ring sling"? If not, what style is it? TIA.
That looks like a stretchy wrap to me. No ring is visible and I can see one loop of fabric going around his waist and another going over each shoulder.
It could be a baby Ktan too.
Could be a Blue Celery
Looks like some sort of wrap. It's hard to tell what kind though.
I'm pretty sure it's a blue celery. I think that grey with the contrast serging is one of their colourways
