This waist extension will only work with the new generation ERGObaby carrier

The ERGObaby waist extension extends the circumference of the waist belt of our carrier by 8", from 43" to 51" on our standard model and from 48" to 56" on our Sport carrier . We do not recommend using more than one waist extension. In addition, we highly recommend that the waist belt on the carrier not be extended further than a one-inch tab. This allows for easier adjustments.
