I use the Intex Challenger 2-person kayak and it works great for being able to just throw in the back of your car. Comes with a big bag that you just throw everything into after deflating. Get the 2 person and just don't put the front seat on it. Provides plenty of room to bring backpack. Durable as well, have definitely cruised over some very shallow and rocky spots on the rivers with no issues. Recommend getting a air pump that connects to your car power outlet (Hand pumping unnecessary work)
