It's a Kelty framed backpack carrier, can't remember the model number off top of my head right now. We were planning on getting a Deuter backpack carrier, but then the Kelty one showed up at less than 1/3 the cost of Deuter carrier I was thinking about buying. My shoulders may regret this decision, but considering we won't be using for more than a short day hike, the price was just too good to pass up.
We remembered liking Ergo, though we ended up with a different brand for one reason for another that we can't remember at this point.
