Kelty Transit 3.0  (Limited Time Offer)

"Great idea, but was not designed with a child in mind. the inside of my son's thighs were rubbed raw during a very short walk to the park and back - 1 hour max. By the time we returned home he was crying and in a lot of pain. The Kelty 3.0 pushes the legs against the main backboard between wearer and child. That backboard is covered in the regular nylon material, which is very rough to the delicate skin of a toddler. There is also a hard seem in the area where my son's legs make contact. I would recommend that this area be covered by the same soft material that covers the top area that's close to the face."

"This has been perfect for our little boy. He is 25 lbs. so he still has lots of growing room. We got the 3.0 on sale through ebags for cheaper than the next model down - which is awesome! One thing to take into consideration. . . I am six feet two inches tall and the Transit 3.0 is perfect because it allows for a taller adjustment than the next model down. Overall, the Kelty backpack has been great. I would buy one again in a heartbeat. We are also looking forward to using it on a trip we are taking to Boston to visit family. I like the idea of carrying my boy and having my hands free rather than pushing him in a stroller or carrying him in my arms."
