We have got two baby-carriers which we use frequently. One of them is the older version Osprey Poco Plus. I can definitely recommend this. They have absolutely thought of everything for the comfort of the baby and the carrier. I see the new version has got the Anti-Gravity hip belt which fits like a dream. The built-in sunshade is also a great feature as it packs away very neatly and it will never get lost. It does cost a lot so my opinion would be on how often you would think of using it. If you are only planning on taking short 30 minute hikes then the entry level options would be more than enough. If you are planning on doing day-hikes with the kids then all the packing space and comfort is definitely the way to go and I would recommend the Osprey.
