We went to Jamaica for 10 days without a stroller and without a diaper bag thanks to this carrier. The extra pockets held 8 diapers, wipes, 4 bottles, formula, food for the day, books and toys for the airplane, my cell, and the baby. It was my carry on, which stored perfectly overhead. The carrier is not for someone who is out of shape. It sits just like a hiking backpack, so if you are not accustom to a backpack, this may not be the best option for you. For me, it could not have been better! Thanks Kelty.
