Made of durable, lightweight, and breathable fabric, the ERGObaby Performance carriers are made to accommodate all active moms and dads. The Performance carriers feature a high-performance polyester exterior, ideal for outdoor activities in all climates; a breathable mesh lining, keeping babies and parents cooler and comfortable; and a cooling panel for extra wicking. The attached sleeping hood stores easily in zippered pocket. This sleek, streamlined design offers a smooth, supportive fit for parents and babies of most sizes, and can still be used to carry babies from newborn to toddler on the back, front, and hip positions. Contoured shoulder straps keep your baby close to your body, eliminating extra strain on your shoulders or back. Thinner foam padding provides cushion without bulk. Waist extends 25"-48" (the Ergo waist extender is NOT compatible with the Performance carriers).
