This Ergobaby baby carrier is made of mesh material for good breathability and features adjustable straps for comfortable carrying. - Brand: Ergobaby - Color: Gray - Material: Mesh - Features: Adjustable straps There are no major stains, but there is some soiling around the neck and shoulder straps. It has been washed. Please refrain from purchasing if you are concerned. As this was my second baby carrier, I don't think the shoulder straps are worn out much. Thank you for looking.
