The ERGO Sport carrier is made of a lighter fabric which offers a slight wicking feature to help keep babywearers more comfortable. A vent in the body of the Sport carrier provides extra breathability, keeping both baby and parent cooler. With a waist belt that can be worn up to 48 inches around (5 inches longer than the Standard & Organic ERGO baby carrier), and shoulder straps that extend 4 inches longer than other carriers, the Sport carrier is a great fit for babywearers of all sizes. Sleeping Hood is completely detachable and can be stored in the pocket.
