I have now been able to use the Deuter Kid Comfort III for a couple of years. I have used this carrier on endless local hikes as well as through National Parks. I have used it in the summer and I have gone snowshoeing with it in the winter. It has made taking the kids to the outdoors a much more enjoyable experience for them and me. I have been impressed by how well it handles the weight of the kids. I have been using it with my boy since he was just over 1 and he still loves to ride in it at 3. It is rated to hold up to 48.5lbs total weight, which includes child and gear.
