MEC backpack carriers for babies/kids

Got this MEC (Mountain Equipment Co-op) backpack as a shower gift and so far it has been great! The picture here is us hiking in Jasper. (Well to be honest we were not actually "hiking" more like walking...) Although my son hates being strapped in, once he is in he loves being carried around in it, I think he loves the view he gets from being so high up. He has also napped in it, I've just put a blanket between his head and the part where the exposed strap is otherwise he gets marks on his head.

However, my husband is always the designated "backpack carrier". I just find it too heavy, maybe I need to adjust it better I don't know, any suggestions? I was wondering if anyone has tried other backpacks and what they thought of them, I know there is a more expensive one at MEC but don't know of any others.

I also like the little canopy (as seen in photo), although my husband thinks it looks dorky, well too bad for him I like how it blocks the sun or shields the rain. Btw - this photo was very recent - note the hat and coats - it was cold and rainy!

I am just amazed at how many things there are available on the market these days to carry babies in. Slings, bjorns, backpacks, well that's only 3 but I'm sure there are more! Maybe I'm just overwhelmed with the selection of each thing, so many different brands and how do you know before you buy which is best? Well hopefully this post will help if you are wondeirng about backpack carriers.
