I'm selling this because I no longer use it. It was really useful for breastfeeding easily while out and about! It's made of thin cotton, so it's breathable (and you can't see through it from the outside), which helped my baby stay cool even in the summer! A large breastfeeding cover made of 100% cotton, gentle on baby's skin. - Material: 100% cotton - Design: Large size - Use: Breastfeeding cover Thank you for looking.
