One warning about kids wearing full-face helmets in general, and Bell convertible ones in particular:
My oldest borrowed my Bell Convertible a few years back. It was a M, same size she wore in het normal half shell.
She had a small crash, and ended up with a gash under her lower lip.
Upon inspection, we found the chin-bar could be pushed down below her chin quite easy. Combined with the large face opening, this left her face pretty much unprotected.
Same thing happened to a friends daughter with her full face.
It seems that even though their head circumference is adult sized, their cheeks and chin are still smaller.
So what we did was:
Got ~6 fullface helmets (regular or convertible) in the proper head size.
Tried them on. Compared how stable the chinbar felt.
Took 4 different sized balls, ranging from bigger than basket ball down to ~4” mini soccer ball, and tested if they could be made to touch her face with each helmet on.
There was a huge difference between helmets. The thickness of the helmet over the forehead matters for this, as did the height of the chinbar in front, how far it protrudes, and how snug it fit on the cheeks.
