Nûby's eco-friendly travel collection is partially made with polyester fabrics made from recycled water bottles. Although not all polyester used in this product is recycled, we strive to use recycled polyester where possible to reduce dependency on fossil fuels and divert plastic bottle waste from oceans and landfills, helping to make our carbon footprint a little lighter.This practical Nûby™ Eco Backpack Safety Harness with Tether helps you keep your child safe and close to you, for those times when you really need it. Ideal for walking, shopping or traveling, your child will be comfortable in the Nûby™ Backpack Harness with its soft and adjustable straps. Plus, the strap doesn't pinch or pull because it is attached to the bag, not the child.
