The best pad is the one that gives you a good night's sleep! If you have to carry more weight to accomplish this, so be it. Are you out there to suffer or to enjoy yourself? I use a 3/4 length Pacific Outdoor InsulMat Max Thermo, which is an insulated air mattress. 17 oz. It's perfect for my old bones! It has been discontinued, but Pacific Outdoor has a very similar model. Your Mileage May Vary!
