FABRIC:The Ergobaby Sport Carrier is made from a blend of 35% cotton/65% polyester, while the Performance Carrier features an exterior of:

• 98% polyester/2% lycra (Grey) 
• 70% nylon/30% cotton (Green)
• 100% polyester (Black)
• 100% polyester (Blue) 

Performance carriers also have a cooling panel for extra wicking, and a 100% Cotton mesh knit lining. 

WEIGHT: Due to the difference in fabrics, the Ergobaby Performance Carrier is about 1/3 lighter weight than the Ergobaby Sport, Original, or Organic carriers.

WAIST BELT: Both carriers have waist belts that can extend an extra 5” past the length of our Original or Organic Ergobaby Carriers, accommodating from 25” to 48”. The waist extension accessory is compatible with the Ergobaby Sport Carrier, but not with the Performance carriers.

SHOULDER STRAPS: The Ergobaby Sport Carrier’s shoulder straps are straight, as the Original and Organic Carriers, and can extend to 27”. The Performance Carrier’s shoulder straps are contoured; feature thinner, non-water-absorbent foam; and extend to 23”, like the Original and Organic Ergobaby Carrier’s straps.

SLEEPING HOOD: The Ergobaby Sport Carrier’s sleeping hood is detachable. The Performance Carrier’s sleeping hood is attached, and stores in the zippered pocket.

CHEST STRAP: The Ergobaby Performance Carrier’s chest strap is on a slider, for easy adjusting.
