Now you can conveniently transport your car seat from one place to another while keeping your hands free. Designed by a mother who frequently travels with her children, the Pac Back is an easy-to-use car seat carrier system. Lightweight and durable, this innovative carrier is manufactured from materials that are built to last: tough, high-density nylon with heavy gauge shoulder straps. A padded waist strap, padded hip protectors and soft padded lumbar support provide comfort while carrying. The Pac Back fits all car and booster seats. If you travel frequently with small children and car seat in tow, the Pac Back is a must-have. If you've ever lugged a car seat, stroller, and carry-on bags through the airport, you will be amazed. It's especially great if you and the kids are traveling on your own. It takes only a few seconds to adjust the straps to fit, clip the seat in, and put the Pac Back on without help from a partner. Please do not carry the child in the carseat while it is on your back.
