This new concept in ERGObaby Carriers is one of our best sellers! Made of a blend of 35% cotton and 65% polyester, the lighter, more-breathable fabric helps to keep babywearers more comfortable. The carrier's body features a vent for extra breathability, keeping both baby and parent cooler. The waist belt can extend an additional 5" further than our Standard or Organic carriers, and the shoulder straps can extend an extra 4", providing comfortable fit for babywearers of all sizes. The Sleeping Hood is completely detachable and can be stored in the pocket.
