I have the Noah 9 and use it for 3 season (kayak camping and hiking). It works great and the tie downs are superb. Rain won't seep thru like sil-nylon. The Noah 12 seems huge but works well for 4 season as you can fold it to make end-walls to block the wind. Got the best prices at Sunnysports. The Hennessy Hex works well for kayak camping also...LOTS of room.
