If you were to have a transforming backpack, what would you want it to turn into? A fully functional lawn chair would probably be a great idea. This chair turns into more than just the average lawn chair, it's also a cooler, becoming a 3-in-1 piece on command.
The bag itself is large, so it can hold onto anything you need to pack into it, but as soon as you need to take a seat it morphs with only a few folds. After it's folded out, the cooler is attached to the side, holding onto all your beers that you were most likely carrying in the bag in the first place.
This is the king of all camping bags, so if you're looking to hit the great outdoors this should be a priority.
