The Big Agnes that I gave a link to is 1lb3oz, dimensions are 72x20x2.5
The Therm-A-Rest ProLite4 is 1lb8oz, dimensions are 72x20x1.5
In my opinion the Therm-A-Rest is going to be much more durable than the air pad. Also, I would think that since the ProLite4 is rated as a four season pad it should have much better insulation. But I was just looking at
this and was pleasantly surprised to find that these air core pads aren't too bad. :idea: I think I may stop by REI today for lunch and find out how much breath it takes to get one inflated properly and lay on it to see how comfy it is. I will post my results.
