The only reason I gave it a 9 is the packability. It comes with a great case for backpacking, but for kayaking you need to get a dray bag for it. It fits fine in my Tarpon 120's smaller hatch. I rigged a grab line around the zipper so it doesn't 'migrate' to the rear of my kayak in transit.
If you overnight kayak this is a must have on any list!!!
