The Goldbug 2 -in-1 Harness Buddy is a animal character backpack with a built in safety strap that adjusts as your child grows. A strong buckle allows easy on-off access meaning that it can be used as a regular backpack when the rein is not required while the connection strap remains securely attached when being used as a harness. The long, 5-foot rein allows your little adventurer to move about while still under your control.
