BabyBjorn Baby Carrier One Air Can be used from newborn to 3 years old. Offers four carrying positions: high position facing parent, forward-facing, and back carrying. Back carrying is easy, can be done alone while standing, and simply involves rotating the baby from the front carry. All buckles can be fastened with one hand in the front. Taking the baby out doesn't require removing the shoulder straps, making it easy even with outerwear on. Features 3D mesh and 3D structure. The shoulder and waist belts have cushioning while maintaining a sleek design. There is some pilling, but it is in relatively clean condition.
