QuickSmart invented a stroller that turns into a backpack.
If you have ever been (or will be) a parent, this is likely to become your favorite tool. Kids want in, then out then into a stroller and they are always needed. If you could just put the stroller on your back, it would be much easier.
This also comes in handy when you are taking the stroller through some tough terrain. Say you are at the park, and you want to take a trail. The young one is going to have to do some walking, but the stroller is safely on the back. It weighs about 9 pounds, which shouldn’t be much if on your back and will come in handy in those airport sprints.
It costs about $160 to $194, which seems like a good price compared to other strollers I have seen and none of then fold up so nicely.
