A child carrier backpack with a machine washable child seat that provides under leg support to maximize comfort on any adventure. Our unique system for this support is called ErgoRide, and in terms of comfort and ease of use, the ErgoRide child cockpit truly delivers. It provides one of the most comfortable rides on the market for a child and lets you experience the freedom to move anywhere. In addition to the traditional support under the child's bottom, the ErgoRide provides extended support up underneath the child's legs to better disperse the child weight. The result? Longer hikes, in comfort! The Thule Sapling Child Carrier has an open and airy feel to help optimize weight and provide adequate ventilation - to keep your child cool on hot summer days.
