It's great that we have so many options in the baby carrier department these days and it seems the trick is to find the one that best suits your family and lifestyle. We're betting the Kokopax carrier, a more recent entry on the scene, will fill a niche for many people.

Frame carriers used to be more popular and we sometimes see very old ones at garage sales, but besides the Kelty carriers which we see used more for backpacking and hiking trips, there aren't many frame carriers on the market nowadays. The Kokopax is lightweight - under 3 lbs - and can be used for kids up to 35 lbs. or around two years old (starting from about 6 months). Having your child on your back seems particularly useful when you have more than one kid to wrangle as it leaves your hands free and could also free you from using an unwieldy double stroller. This also strikes us as a very dad-friendly option. 
At $179 the Kokopax is more expensive than most carriers we've seen (including the popular Ergo which also allows for back carrying), but if you do a lot of walking and baby carrying it could be a wise investment. You can check out all six fabric designs and read more here.

this looks like the bars would hurt/dig in to my big fat momma hips! does it adjust?
holy crap that's expensive. i think i paid a couple of dollars at a garage sale for my used 1980's era one and $50 for my larger gently used Kelty. sure these are a lot prettier than either of mine, but for the price? not worth it to me! check Craigslist for these type of frame carriers...that's where i got my larger Kelty. a lot of people seem to buy these for one hiking trip or vacation, then never use them again.
cute fabric choices!
I personally love ergo-type carriers because they have a padded waist, whereas this carrier looks like more of the weight is on the shoulders? I have a kinderpack and it is hands down my favorite carrier:

i'm with selena on this one. it's cute but looks horribly uncomfortable. i'm an ergo user and can't go back to anything without waist support.
too expensive, but my parents had one very similar to that. my dad used to work in the garage with a toddler on his back. :)
The Ergo is very comfortable for back carries; however frame backpacks have the advantage of sitting the child up higher so they can see up over your shoulder (my son is always straining to look around me when he is on my back in the Ergo). I agree that this particular carrier would be better with a waist strap and an additional buckle across the chest.
It's pretty though!
