I'm not just saying it because I have one, I'm writing this as a seasoned engineer and a cautious father of 3. I've been on my endless research for a practical/safe/affordable/versatile backpack carrier that provide comfort for both the baby and the parent. This is it.
The frame is sturdy yet light-weight and well-cushion. Both the baby and the parent won't feel it. Yet get the total benefit of a sturdy carrier. I've left my baby in and to see if it can be standing on their own on carpet/hardwood/grass/tile... it does stand very well.
Many pockets of course, it doubles as a diapers and snacks backpack when you go outdoor! Excellent value!
