This is an Aprica baby carrier. I bought it, but I haven't used it much, so it's in clean condition. It uses breathable mesh material, which makes it less likely to get stuffy during times when you sweat easily. Also, the shoulder straps are designed to fit snugly, and the waist belt has support pads, which I think made it less likely to put a strain on the shoulders and lower back. For when you're carrying your baby or carrying them on your back. For those who understand, Thank you. Carry style... Forward-facing carry Carry style...
