comfort and storage
This is my 3rd kid carrier brand. We used this carrier for 2yr old and almost 4yr old on many hikes. We liked the harness for us and harnessing for them. Also it comes with stirrups for the kids, a sun/rain hood, lots of storage for our stuff and theirs and my wife really liked that it didn't look like an expedition pack (I didn't notice) but it is comfortable!
