Your little baby is finally ready to spend hours under the sun, but not quite ready to walk the trail on their own--this is the precious period of time you get to carry your child on your back using the Journey Perfectfit Backpack by Kelty. Designed with a wide seat base and adjustable foot stir ups, your growing child can comfortably rest in the safety of the five-point harness. And for the parents' comfort, this pack is equipped with Kelty's PerfectFIT suspension system that easily adjusts so both parents can share the load. Padded mesh shoulders and waist belt give you a supported fit for heavy loads, and comes with a quick-access pocket for an emergency on-the-go snack so you can maintain momentum. A large zippered pocket at the back holds everything you need for you and your child to enjoy a full day of hiking.
