The fabric is light and thin but not transparent. Now that the weather is warmer and better, I think it's ideal. Finally, the child should not get a heat buildup while drinking. However, it is correct that the buttons are rather small and the cloth (do not bother me) rather takes the form of a wide scarves. But as I said, as always wearing it as a poncho, it's front and rear wide enough. So from me five points for this practical part, with which I've got to stop worrying about breastfeeding in public.
